I'm going to add one to your list... Steve Vai and Eric Sardinas!!!! I saw them at the House of Blues in Chicago and it kicked ass. If you haven't heard Eric Sardinas play before or seen Steve Vai play before... definitely check it out! I never heard any of Sardinas' stuff before but after that concert I'll be a fan of his for the rest of my life. He was just as much fun to watch as Vai was. He plays heavy blues stuff and it's AAAAAAALLLLLLLLL slide guitar (with distortion, sounds awesome). He can definitely shred it though. He's a good vocalist too. So check it out!
