Boston. Doesn't even matter that Brad's no longer here. Tom Scholz has one of my favorite guitar sounds ever. It's completely unique and I have to hear it live someday.
Electric Wizard. For the sake of furthering my hearing loss and enjoying every minute of it.
Pentagram. Sabbath invented doom. Pentagram perfected it.
Blue Murder/John Sykes. I'd prefer the former, but I must see Sykes in some capacity. One of my favorite guitarists.
Gonna actually see this one this summer. Alice Cooper as a headliner.
