Just got my copy of Joe Satriani's Strange Beautiful Music on 2ch/MC SACD yesterday. I'm pretty impressed. Aside from the (unfortunately predictable) occasional "overuse" of the surrounds, the disc sound superb. I definately heard a lot more details that weren't readily apparent in the (excellent sounding) CD version.
I think the disc is a hybrid, forgot to check. My CD player won't play every CD/SACD hybrid disc I've tried, unfortunately.
Musically, this is a great one, maybe not as good as Engines of Creation, but nonetheless excellent. If you like Satch, this is definately an SACD I'd recommend.
