how about some avant garde? henry grimes, alan silva, barry guy, mark dresser.
mark dresser makes some insane sounds with his bow.
he also uses a pickup that amplifies overtones and other sounds that are usually missed that's mounted over the nut of his bass... i was kind of wondering if anyone knew anything about it. i have no idea what it is, i found a page one time that explained it, but i'm not a tech guy so it didn't make much sense to me. any clues?
oh, and alembic makes the classico. does that count?
