Tracy Lisk is a percussionist who mainly performs on drum set, based in Philadelphia PA. Lisk's history as a painter informs the substance of her improvisations which contain references to rhythmic structures while maintaining a fluid, suspended continuity.

Lisk has a background in Brazilian percussion and has worked with master drummers in Salvador, Bahia and Rio de Janeiro, Brazil, and performed in, as well as lead percussion ensembles in Philadelphia. She has collaborated with William Parker, saxophonist Gary Hassay, Andrea Pensado (electronics/voice), dancer Ryuzo Fukuhara (JP, SI), Mia Zabelka (AU), and cellist Helena Espvall (PT), among others.

In September 2023 she played with Susanna Ferrar, Maggie Nicols and Sylvia Hallett at the ImproMonday Festival in Zagreb. [Lisk is also a member of London Improvisers Orchestra]

"Andrea Pensado began playing piano as a girl, with private instruction.

She obtained her BA in Music Education from the University of La Plata in 1987. Immediately following, she moved to Poland where she continued her studies at the Krakow Academy of Music. Pensado graduated in Conducting of Vocal and Instrumental Ensembles in 1992 and in Composition with honors in 1995. Her professors were Barbara Buczek and Boguslaw Schaeffer in composition and Marek Choloniewski in computer music.

The music of that time shows a wide variety of interests, from pure instrumental to mixed genres such as instrumental theatre, live electronics and text sound compositions. During this period, she was invited to participate in numerous festivals and workshops, as a result of which her music was programmed in Poland, Austria, Germany and Holland.

"In 1997, she moved back to Buenos Aires. In 1998, she cofounded an interdisciplinary duo (Qfwfq) along, with Gregory Kowalski (in charge of the images). While still in Buenos Aires, the duo often worked with the collaboration of solo performers (Martín Moore, Lucio Capece, Adriana de los Santos, among others). They presented their work in many events in Buenos Aires, including the Cycle of Electronic and Experimental Music (in the Museum of Modern Art); the International Sound Art Festival EXPERIMENTA; the Cycle of Contemporary Music at the San Martin Theatre; the Experimental Video Festival (in the Museum of Fine Arts) and the Ricardo Rojas Arts Center.

In 2002, Pensado moved to the USA. At first, she continued performing with Qfwfq, mainly in the Boston area. The duo channeled most of her artistic work from 1999 to 2009.

Presently, Pensado performs extensively in the US, both as a solo artist and in frequent collaborations with other musicians. She also tours outside the US and has been featured in Brazil, Poland, Germany, Russia, Lithuania, Latvia, Estonia, Finland, UK, Portugal, Hungary, Canada, Italy and Austria.

She continues using Max as her main programming tool. The approach to programming and performance is highly intuitive. Occasionally, the combination of the performance situation, the often abrasive sounds, the irrational use of the voice and the inherent uncertainty of improvisations contributes to discoveries of unknown places in her mind."
