ZZ Top Nirvana Grand Funk Railroad Rush ELP Ben Folds 5 (The Who & Zeppelin) (three instruments, but not really a 3-piece) I've been getting back into ZZ's Tres Hombres lately since I'm trying to listen to more 3-piece bands to see how they fill out the sound. I've already gone to school on Entwhistle, Geddy and JPJ. But who am I overlooking? More like Early ZZ Top and Grand Funk? Someone current or recent worth a listen. Sparse bands that don't sound sparse. Would prefer bands with a bassist, so White Stripes, Black Keys & Suicide don't really hit the mark in this case. (But I love those bands).
