This is rough...real rough. It depends on how nostalgic I am being....
Fugazi - Steady Diet of Nothing - of course not their best, but it was the first one I ever bought of theirs - had bad tape copies of everything else until I sold a bunch of really bad CDs (back when they still came in those big long boxes) to get Steady Diet.
Dinosaur Jr self titled, damn, loved that album in high school
Paul Weller - self titled, just damn good...though I listen to others more, its still my all time fav
Tom Waits - Mule Variations
Charles Mingus - hard choice, catch me on one day and it'll be Ah Um, Oh Yeah or Charles Mingus Presents Charles Mingus
Ornette Coleman - Shape of Jazz To Come
Jim Pepper - Comin and Goin
Michael Blake - Kingdom of Champa
Super Furry Animals - Rings Around the World - was listening to it when I found out about 9/11...At Least Its Not The End Of The World specifically....
And one that I always love to put on is fIREHOSE Live at the Totempole EP
I just have MP3s because I sold it ages ago when going through a jazz phase, needed cash and because I was generally a SLACKMOTHERFUCKER!
