I LOVED the early clash albums, London Calling being a classic! I lost that album quite some tiime ago. I was most partial though to their self titled album- all of my favorite classics- Im So Bored with The USA, Janie Jones, etc.. I also really liked The Guns of Brixton. I remember when I was a kid one of my friends mom would sometimes drive us to school in the mornings.... shed BLAST The Guns of Brixton.... in her Volvo 740 wagon! We lived in upper middle class suburbia, and im sure the other soccer moms were pointing thier noses in disgust as we'd pull up.. LOL. We'd end up singing along with my friends mom.

Most of the time tho she listened to NPR.
BUT my all time favorites are early Yes ( South Side of The Moon, Heart of Sunrise etc.) Can, Holger Czukay, early King Crimson, and the electronic pioneers of the 60's- the Silver Apples.
Can's "I want more" is one of my favorites, and Oscillations by the Silver Apples.... if you havent heard them, check em out... its hard to believe what they were doing in the 60's..... ingenious!!
