The Wrecking Crew My musician son Will got me a ticket to a screening in a few weeks in San Francisco of the 2008 documentary, The Wrecking Crew. They were a mostly unheralded group of musicians who played backing for the Beach Boys, Sonny & Cher, the Mamas and Papas, and were Phil Spector's Wall of Sound. It's hard to see this, as it's never been released (I think they can't get funding to pay for copyright permissions for all the songs) and I'm excited to be able to see it.
Grooveshark I've said it before, but this is a tremendous resource for music lovers. You can play any song or any album. Not download, but play. I'm surprised by how complete it is.
