That's mainstream music, It gets old. They have songs that'll rock you but you would have to get the albums to hear 'em. I have lots of favorite songs because they're good.
I only listen to the songs of the original BOC cast because I like the boys. They're still going but only two members are original today, Eric and Buck.
All members of GFR are really talented, they know their instruments. Mel with his bass guitar is the best bassist I've heard. I have the DVD of this concert, CalJam74.
By the way, check out Mark's guitar. It's all aluminum.
