PascAli - Suspicious Activity (Creative Sources 2012)

"PascAli is the duo of American Sean Ali and Franco-German Pascal Niggenkemper, both of whom play prepared double bass. The twenty-two tracks presented here are brief pieces meant to show the sheer diversity of sounds that can be produced by acoustic basses properly prepared. And that diversity is truly fascinating.
The CD literally begins at the bottom. The first track is an improvisation for the instruments’ endpins—squeaking as they’re loosened and tightened, whispering as they’re bowed. Subsequent highlights include “How Long Does It Take Styrofoam to Become Earth Again?” which is a hissing of white noise as the bassists bow Styrofoam; “Witch Tricks,” with its spiccato (bouncing) bowing and squeaking pulse evolving into overpressured bowing and percussive strikes; and the sparse pizzicato and metallic sounds of “Japanese Garden." - Creative Sources
