Jeff Healy was one of the best, his death was a real shocker and huge loss for music.
My pick for this year so far has to be Dream Theater-Greatest Hits (and 21 other pretty cool songs).
This is the kind of release that makes you look into the back catalog of a band. In this case I have every CD by DT and I am always listening but its always nice to have the best put together on one or two CDs and then other tibits like rarities and "previously unreleased" tracks.
