Steve Taylor. Definitely. He's about 6'6", maybe 140 lbs soaking wet, and has been known to do cartwheels across the stage. He's the most energetic performer I've ever had the pleasure of seeing. I've seen him in concert five times in the last 16 years.
Other notables include Tom Petty, Mike and the Mechanics, Glass Harp, Joe Satriani, World Wide Message Tribe, Newsboys (seen them 14 times) the Neville Brothers, King's X, Johnny Cash, Gaelic Storm, the Canberries, and Iona.
I used to average a couple dozen concerts a year when I was in my teens and early twenties, sometimes as many as two or three a week. Nowadays with a wife and two young children, I'm lucky to make it to a coupple live shows a year. We're fortunate to have a really good Irish Festival close by every year (in Dublin, OH), and we try to make it a priority to go every year. Lots of great Irish and Celtic music from many nationally and internationally well known groups.
