I've been a fan for decades and they are serious musicians combining many genres. The original 6 guys together were downright amazing. The chemistry between them made them the superstars they became.
Jerry Eubanks is the one who plays the flute and sax. He's a real pro, the music teacher type if you know what I mean. Let me suggest their DVD "Live from the Garden State, 1981". If you can play concert DVDs over a surround sound system, then get this. The audio is not the absolute greatest but decent for a performance of 28 years ago. George McCorkle (guitar) on "Searching for a Rainbow" is one you can't miss. The performance of a lifetime. The only genre I'm not a big fan of is their "western" style songs with a bit too much country. Otherwise, fantastic.
Do you ever wonder why some bands just make it to the big time? While certainly it's a lot of hard work, talent, and great management, it's also the chemistry as I call it between the players. Something just clicks and the symmetry happens. Like the Fab Four for example. Four youngsters from an industrial port town like Liverpool with no formal educations and look what happened. That never ceases to amaze me.
