W.I.T.C.H. (We Intend to Cause Havoc!) — Zamrock / psychedelic rock / funk-rock / garage rock, combining 1970s psychedelic and hard rock with funk and traditional Zambian/African rhythms. Think fuzzy guitars, wah-wah, funky grooves, psych-rock.
Forty Feet Tall — post-punk / alternative rock / indie rock, with strong grunge and psychedelic-rock elements. They're considerably more modern, aggressive, angular, and punky. The band itself describes its current sound broadly as post-punk.
