A Capella group of six open'd for us yesterday in Wildwood NJ..The group is great, you can check them out WWW.lunaticgroove.com They have a tune from rehersal on their site, but this does not do justice to their polished performances...There are no instruments, vocal drums/percussion, and vocal bass..At our show they were unbelievable...One of the guys [Joe] is our drummer's son..
