If you love Marco, get "The Aristocrats" CD. They do a killer semi-jazz-fusion with a LOT of rock influence. They are just brutally good players that pull it all off perfectly live, too. I got to watch them from just a few feet away here in Indianapolis this year and was blown away. I just wish I could have gone to California for the recording of their to-be-released DVD.
They're fairly active on Facebook, too.
