Classical and rock mainly, though I keep an open mind and ear. For the former, I particularly enjoy baroque, late romantic, and early 20th-century works. For the latter, mainly metal (the real thing: old Metallica, Megadeth, Black Sabbath, etc., not 80's pop metal hair bands), classic punk, alternative/college rock, classic rock (Zep, Hendrix, etc.). I also like some new-agey electronic stuff, like old Tangerine Dream.
