Jimi Hendrix, Gil Scott-Heron, Curtis Mayfield, Band of Gypsies, The Animals, Rolling Stones, Lynyrd Skynyrd, Country Joe and The Fish, Canned Heat, Jefferson Airplane/Starship and of course, the one and only, Janis Joplin.
Really, I listen to everything. But these days I listen to a lot of post-punk from the early 80s. I am also big into synth pop and electropop -- new and old. I also try to keep up to date with the GOOD music that is being released at the moment. But really, I listen to pretty much all genres. My first love was 60s psychedelia, then I was big into prog for a while, as well as a lot of experimental music from Germany. For the past couple years, though, post-punk is what I listen to most probably.
