You're quite welcome, I'm always happy to turn people on to good music. I'll also suggest some more popular stuff like Sammy Hagar, VH, The Cars, Iron Maiden, Thin Lizzy, etc, just in case you guys aren't familiar. Also, if he has any blues leanings, a lesser known guy named Rory Gallagher is really excellent, as well as (of course) Stevie Ray Vaughan and Clapton.
