It's only rock and roll...
Like Facebook's call to connectivity, the Rolling Stones' 1975 recording sessions was a social networking scene of guitarists trying to fill the void after Mick Taylor had mysteriously de-friended the band. Billy Preston, Harvey Mandel, Wayne Perkins, and it's said maybe even Jeff Beck and Eric Clapton played on this eclectic record, a mash-up of styles with a groovy groove but no defined direction.
It's only Facebook but I like it.
