Music Info Websites

[Mahombi]

Does anybody know of any websites that specialise in information on rock and pop music? I'm looking for information on a number of bands and their past concerts and recordings. I've been googling individual band names, but it's painfully slow, searching through the hundreds or thousands of possible links.

http://rateyourmusic.com/ has information on recordings and is written by fans. Also includes all live recordings and bootlegs etc. Not neccesarily 100% correct but full of information. Another useful site is http://www.allmusic.com
