i tend to go for more fluid, spacey (if you will) stuff. course that depends on what one thinks "fluid" means, but for example i'm really into early Verve (the boys from Wigan, England, not the jazz label) - their first record is like nothing else i've ever heard anywhere ever - it's so amazing (nothing like that "bittersweet symphony" stuff - good music but nothing like what they used to be in the early 90's). it's called "a storm in heaven." also, i adore Spiritualized/Spacemen 3, Flying Saucer Attack, Colfax Abbey, Bardo Pond, Slowdive/Mojave 3, Brian Eno, Windy & Carl, Roy Montgomery, Low, The American Analog Set, The Olivia Tremor Control/Circulatory System and Morphine to name the spine of my collection so to speak. a lot of it is improv - there's nothing better than hearing the verve play a 14 minute improv "gravity grave" or spiritualized doing "shine a light" for example. there is a lot of bootleg trading for the verve from the early years and i have some of them and i really have never heard anything else quite like it. it's similar to some stuff sort of, but takes it further and in different directions than anyone else that i know of.
i of course like many other things, like the classics - rolling stones (esp. early stuff), zeppelin and rush of course, jeff/tim buckley, nick cave, blues in general, black crowes are a good modern rock n roll band i think (they're tight live), i like OK computer by radiohead and some of the new stuff, but they're a bit pretentious for me.
i think tool is a great band and they're really talented and technical, absolutely. most top 40 current stuff is shite as far as i'm concerned, britney beers and linkin fart and whatnot. i am an avid classical guitar player and fan, love classical music of all sorts (chopin, rachmaninov, mendelssohn, ludwig van of course being some of my favs) and indian classical music too. but there's just something about phish that makes me cringe, totally rubs me the wrong way. i think part of it is the atmosphere and the baggage that goes along with it for many of their fans. mostly it's just the music that i can't listen to though. i do have a friend, however, who knows them (phish) personally and says they're great guys and good friends and great fathers/family people so i respect them and they're doing what they love and that's great. and i don't have anything against their fans either, it's just something i don't want anything to do with. it's hard to explain. their musical energy is on an end of the spectrum i generally stay away from. sometimes i get mouthy calling them "miserable clowns" and whatnot but i don't mean anything really derogatory or hurtful, i just feel strongly about certain types of music both positively and negatively and it comes out kinda harsh. i'm sorry for the long post, just trying to explain myself well.
