"Born in 1961 in São Paulo, Brazil, Perelman was a classical guitar prodigy who tried his hand at many other instruments - including cello, clarinet, and trombone - before gravitating to the tenor saxophone. His initial heroes were the cool jazz saxophonists Stan Getz and Paul Desmond. But although these artists' romantic bent still shapes Perelman's voluptuous improvisations, it would be hard to find their direct influence in the fiery, galvanic, iconoclastic solos that have become his trademark.

Moving to Boston in 1981, to attend Berklee College of Music, Perelman continued to focus on mainstream masters of the tenor sax, to the exclusion of such pioneering avant-gardists as Albert Ayler, Peter Brötzmann, and John Coltrane (all of whom would later be cited as precedents for Perelman's own work). He left Berklee after a year or so and moved to Los Angeles, where he studied with vibraphonist Charlie Shoemake, at whose monthly jam sessions Perelman discovered his penchant for post-structure improvisation: "I would go berserk, just playing my own thing," he has stated.

Emboldened by this approach, Perelman began to research the free-jazz saxists who had come before him. In the early 90s he moved to New York, a far more inviting environment for free-jazz experimentation, where he lives to this day. His discography comprises more than 50 recordings, with a dozen of them appearing since 2010, when he entered a remarkable period of artistic growth - and "intense creative frenzy," in his words. Many of these trace his rewarding long-term relationships with such other new-jazz visionaries as pianist Matthew Shipp, bassists William Parker, guitarist Joe Morris, and drummer Gerald Cleaver.

Critics have lauded Perelman's no-holds-barred saxophone style, calling him "one of the great colorists of the tenor sax" (Ed Hazell in the Boston Globe); "tremendously lyrical" (Gary Giddins); and "a leather-lunged monster with an expressive rasp, who can rage and spit in violence, yet still leave you feeling heartbroken" (The Wire). Since 2011, he has undertaken an immersive study in the natural trumpet, an instrument popular in the 17th century, before the invention of the valve system used in modern brass instruments; his goal is to achieve even greater control of the tenor saxophone's altissimo range (of which he is already the world's most accomplished practitioner).

Perelman is also a prolific and noted visual artist, whose paintings and sketches have been displayed in numerous exhibitions while earning a place in collections around the world."

"Jason Stein was born in 1976 and is originally from Long Island, New York. Stein is one of the few musicians working today to focus entirely on the bass clarinet as a jazz and improvisational instrument. He studied at Bennington College with Charles Gayle and Milford Graves, and at the University of Michigan with Donald Walden and Ed Sarath. In 2005, Stein relocated to Chicago and has since recorded for such labels as Leo, Delmark, Atavistic, 482 Music and Clean Feed. Stein has performed throughout the US and Europe, including performances in festivals in Lisbon, Cracow, Utrecht, Barcelona, Debreccen and Ljubljana. He has had the opportunity to perform with a number of exciting local and international musicians including: Michael Moore, Jeff Parker, Oscar Noriega, Rudi Mahall, Ken Vandermark, Rob Mazurek, Jeb Bishop, Ingebrigt Haker-Flaten, Urs Leimgruber, Pandelis Karayorgis, Fred Lonberg-Holm, Tony Buck, Eric Boren, Kent Kessler, Tobias Delius, Michael Zerang, Michael Vatcher, Peter Brotzman, and Wilbert DeJoode."
