I dont really think The Chemical Brothers are that great tbh... But I am fond of them, I reckon Exit planet dust was one of the 1st cds I ever bought new.
I think the actual 1st cd I ever bought was Monster by REM, but that was 2nd hand.
Growing up I really hated The Chemical Bros, also The Crystal Method. They were just played the fuck out, every day, by a lot of people I knew. The Prodigy and Daft punk were much the same, but I couldn't deny how good that shit was.
