Grateful Dead musicians Bob Weir and Bill Kreutzmann got the celebrity treatment over New Year’s Eve, as they celebrated the holiday at a star-filled private engagement in Hawaii. The two collaborated with Heartbreakers’ guitarist Mike Campbell, as well as keyboardist Todd Stoops and bassist Reed Mathis. According to Stoops, a similar band also backed up blues legend Taj Mahal at the event, who had stumbled upon the party while walking down the beach.

Stoops said, “What a way to ring in a new year! It will be hard to top it in years to come!! I had the honor of playing my favorite music with Billy Kreutzmann, Bob Weir, Mike Campbell and Reed Mathis – then ringing in the new year backing up Taj Mahal with the same cats. Unreal.”

A slew of A-list celebrities were in attendance at the high profile party, including Ben Stiller.
