Break out the sheets of acid.

Just a week after confirming their first tour in five years, the reunited Dead are booked to rock the Mid-Atlantic Inaugural Ball in Washington, D.C. on January 20th. “A DJ will open up — it’s a long, strange trip!,” Mickey Hart jokes to Rolling Stone (the DJ in question is celeb spinner DJ Cassidy). “[Barack Obama] picked us specifically,” he adds, “so it was quite an honor. There was a short list and we made the cut.”

As for the most important question — can the band jam at the ball? — Hart is dubious: “It’s pretty tight, about an hour set. When you play these kinds of things you say, ‘How can I be of service?’ The entertainment committee makes it so that it fits into their huge schedule.”

Another pitfall of political rocking: a background check. “It gave me pause when I had to get a security clearance to play a gig!” Hart says. So did they get past the security scan? “Oh, yeah, we don’t look so bad on paper. It’s not as bad as you might think.”
