GRAMPUS  is an improvising, interface driven trio based in Los Angeles. Using custom user built interfaces for computer, both trumpet player Louis Lopez and trombone player Daniel Eaton create elaborate ways of modifying their acoustic instruments. In developing these new digital instruments, the search for integrating acoustic and processed sound through improvisation led them to the percussionist Michael Lockwood. Together they have developed a sound truly unique that takes full advantage of pulse and augmented timbres. In their live performances they incorporate visuals that are controlled by their instruments in real time, creating a complete immersive environment. The members of Grampus seek to expand their musical vocabulary and explore new modes of creating.

Grampus released their debut album “Ilk Ilk” on pfMENTUM records to wide acclaim. Along with extensive radio play across the US and Europe, “Ilk Ilk” has appeared on the KDVS TOP Ten Jazz Chart amongst the likes of Henry Threadgill, Ravi Coltrane and Wadada Leo Smith. Their music has been featured in the work of Stephanie Zaletel’s dance company, szalt. Their collaborations have been performed at the Sharon D. Lund Dance Theater, Live Arts LA, and at the Walt Disney Concert Hall’s REDCAT Theater.
