I saw R.E.M. back at MSG in the early 90s and it goes down as one of my favorite concert experiences ever. They completely blew my socks off and I have had mad respect for the band ever since.
This is why I'm extremely excited for the new music they are releasing. Their new album Collapse into Now is getting ready to drop (pre-order it today) and their second single off the album is this song "It Happened Today". Its pretty stellar. Especially because Eddie Vedder and Joel Gibb are providing the background vocals.
