May not be what you're looking for, but i relly dig these:
Vincent Courtois - Translucide
David Fiuczynski - Kif
David Eyges - Ace (Electric Cello, No Guitar, but who
needs one)
Louis Sclavis - Napoli's Walls or L' affrontment des
pretendents
Koch/Schutz/Studer - Chocshut or Hardcore Chamber Music
Bill Frisell - Lookout For Hope or Before We Were Born or Where In The World
Erik Friedlander - Grains of Paradise or Maldoror (solo cello)
Alamaailman Vasarat - any
Uzva - Tammikuinen Tammela
Cello is big favorite w/ me, but seems to often be an in between instrument. There's alot of overlap w/ Viola, Cello and Acoustic Bass and alot of overlap w/ electric Cello and Electric Guitar. At a Frisell concert w/ Hank Roberts (Cello) there was no easy way (or point) in trying to separate who was doing what. Definitely an artistic high point for both players, (i think they are both on the Richter 858 cd).
