"Saxophonist and composer Nick Mazzarella has been a consistent presence in Chicago's music scene since the early 2000s, and his regular performances there represent an aesthetically unique contribution to the city's rich jazz and improvised music culture. His working trio and quintet have served as the primary vehicles for his endeavors as a composer and leader, while as a collaborator or sideman he has performed and recorded with such artists as Tomeka Reid, Makaya McCraven, Hamid Drake, Joshua Abrams, and Rob Mazurek. He has released recordings as a leader on Nessa Records, Clean Feed Records, and the International Anthem Recording Company imprint, among others, and has performed throughout the United States and Scandinavia. Mazzarella also curates two concert series: the Anagram Series, presented weekly at Elastic Arts in Chicago, and the Ratchet Series, presented monthly at Cafe Mustache in Chicago."

"Dave Rempis was born in Wellesley, Massachusetts on March 24th, 1975. He began his musical studies at the age of 8, inspired by a family friend who played clarinet in local Greek bands, and by Zoot, of the Muppets Band, to pick up saxophone. During high school he performed in his town, district, and all-state bands and wind ensembles, as well as in a jazz combo at a local music school.

In 1993, Rempis began a degree in classical saxophone at Northwestern University with Frederick Hemke. Finding this environment stifling, Rempis quickly ditched the music degree to pursue studies in anthropology and ethnomusicology. As part of these studies, he spent a year at the International Centre for African Music and Dance at the University of Ghana, Legon, studying African music and ethnomusicology. He also continued to perform with many different types of groups, ranging from highlife and reggae bands while in Ghana, to jazz, free jazz, funk, and contemporary music ensembles at home. He graduated from Northwestern in 1997.

Upon graduating, Rempis decided to focus on performing, and in March of 1998 at the age of 22 was asked to replace veteran saxophonist Mars Williams in the well-known Chicago jazz outfit The Vandermark Five. This opportunity catapulted him to notoriety as he began to tour regularly throughout the US and Europe playing clubs, concert halls, and festivals on both continents.

During his tenure with The Vandermark Five, Rempis also began to develop the many Chicago-based groups and international collaborations for which he's currently known, including The Rempis Percussion Quartet, The Engines, Ballister, Rempis/Abrams/Ra, Wheelhouse, The Rempis/Rosaly Duo, and The Rempis/Daisy Duo. Many of these groups have been documented on the Okkadisk, 482 Music, Not Two, Clean Feed, Solitaire, and Utech record labels. Past collaborations have included performances with Paul Lytton, Axel Dörner, Peter Brötzmann, Hamid Drake, Steve Swell, John Tchicai, Roscoe Mitchell, Fred Anderson, Kevin Drumm, Paal Nilssen-Love, Nels Cline, Tony Buck, and Joe McPhee. Rempis has been named regularly since 2006 in the annual Downbeat Critics's Poll as a "rising star" on alto saxophone, and as a "rising star" and "established talent" on baritone saxophone.

Aside from performing, Rempis is also active as a presenter. Since 2002, he's curated a weekly Thursday-night concert series for the Elastic Arts Foundation. The series has featured over 500 concerts by some of the best improvisers from around the world, while maintaining a focus on up-and-coming local musicians. In late 2005, Rempis helped form the presenters' collective Umbrella Music, working with a small group of musicians and presenters in Chicago to provide better playing opportunities for creative and improvising musicians. As part of this group, he organized the annual Umbrella Music Festival from 2006-2014.

Rempis is also one of the main organizers of the indie-rock Pitchfork Music Festival, a 60,000-person event which takes place in Chicago's Union Park every July."

"Mars Williams is an open-minded musician, composer and educator who commutes easily between free jazz, funk, hip-hop and rock, Mars has played and recorded with The Psychedelic Furs, Billy Idol, Massacre, Fred Frith, Bill Laswell, Ministry, Power Station, Die Warzau, The Waitresses, Kiki Dee, Pete Cosey, Billy Squier, DJ Logic, Wayne Kramer, John Scoffield, Charlie Hunter, Kurt Elling, Swollen Monkeys, Mike Clark, Jerry Garcia, Naked Raygun, Friendly Fires, The Untouchables, Blow Monkeys and virtually every leading figure of Chicago's and New York City's "downtown" scene.

John Zorn credits Mars as "one of the true saxophone players--someone who takes pleasure in the sheer act of blowing the horn. This tremendous enthusiasm is an essential part of his sound, and it comes through each note every time he plays. Whatever the situation, Mars plays exciting music. In many ways he has succeeded in redefining what versatility means to the modern saxophone player."

In 2001 Mars received a Grammy Nomination for Best Contemporary Jazz Record with his group Liquid Soul.

Despite his busy touring schedule with Liquid Soul and The Psychedelic Furs, Mars manages to stay active on the Chicago underground improvising scene. In recent years he has toured and recorded with the Peter Brötzmann Tentet, Switchback, Full Blast, Scorch Trio, the Vandermark 5, Boneshaker, Chicago Reed Quartet and Cinghiale, teaming him with such musicians as Ken Vandermark, Hamid Drake, Michael Zerang, William Parker, Ikue Mori, Kent Kessler, Fredric Lonberg Holm, Peter Brotzmann, Joe McPhee, Paal Nilssen-Love, Ab Baars, Mike Reed, Jeb Bishop, Harrison Bankhead, Dave Rempis, Kidd Jordan and Matts Gustafson.

He performs weekly in Chicago along with Jim Baker, Steve Hunt, and Brian Sandstrom in the improvising quartet "Extraordinary Popular Delusions". As a bandleader, he continues to perform and record CDs with his own free-jazz groups, the NRG Ensemble, Witches & Devils, Slam, XmarsX, Mars Trio, Boneshaker and The Soul Sonic Sirkus which features improvising musicians and aerial circus performers. Along with Die Warsau's Van Christie, Mars has started Ratking Music, a production company focusing on music for film and television.

In addition to performing and creating music, Mars has been an educator in the field of woodwinds and jazz improvisation for over thirty years. Mars held the position of Woodwind Instructor at Bard College for two years. In the last few years Mars has presented Master classes and clinics to a number of private and public institutions including, the University of Massachusetts, Amherst, the University of Chicago, Roosevelt University (Chicago, IL), and June Collins Smith Museum of Fine Art (Auburn, AL)."

"Born in Warwick, Rhode Island on September 22nd, 1964, Ken Vandermark began studying the tenor saxophone at the age of 16. Since graduating with a degree in Film and Communications from McGill University during the spring of 1986, his primary creative emphasis has been the exploration of contemporary music that deals directly with advanced methods of improvisation. In 1989, he moved to Chicago from Boston, and has worked continuously from the early 1990's onward, both as a performer and organizer in North America and Europe, recording in a large array of contexts, with many internationally renowned musicians (such as Fred Anderson, Ab Baars, Peter Brötzmann, Tim Daisy, Hamid Drake, Terrie Ex, Mats Gustafsson, Devin Hoff, Christof Kurzmann, Fred Lonberg-Holm, Joe McPhee, Paal Nilssen-Love, Paul Lytton, Andy Moor, Joe Morris, and Nate Wooley). His current activity includes work with Made To Break, The Resonance Ensemble, Side A, Lean Left, Fire Room, the DKV Trio, and duos with Paal Nilssen-Love and Tim Daisy; in addition, he is the music director of the experimental Pop band, The Margots. More than half of each year is spent touring in Europe, North America, and Japan, and his concerts and numerous recordings have been critically acclaimed both at home and abroad. In addition to the tenor sax, he also plays the bass and Bb clarinet, and baritone saxophone. In 1999 he was awarded the MacArthur prize for music."
