Check out this excellent Rolling Stone review of a recent live performance by John Mayer, featuring Loop Loft artist, Bob Reynolds, on saxophone.  John and his band are currently touring the US this summer, so be sure to catch a show if they play a town near you.  

If you've downloaded Bob's loop collection, bring your hard drive to the concert... there is a chance he will personally autograph it.  There is even a greater chance that security won't allow you into the venue.
