If I can't have Ry Cooder please consider David Lindley. He was absolutely brilliant in the 70's when he pioneered a lot of weird and interesting guitar techniques. His work with Jackson Browne is probably his most well-known stuff but El Rayo-X also warrants attention.
Cooder and Lindley hold an important place in rock music history. Since Rock Band is being used as a platform to introduce players to rock history I think it would be appropriate to include the work of at least one of these guitarists. As a bonus, these guys are relatively unknown nowadays so their music would be a pleasant surprise for gamers.
Thanks.
