There's a scene in "Monty Python and the Holy Grail" where, in the midst of an outbreak of the plague, a town crier walks alongside a cart loaded with bodies and repeatedly hollers for residents to "bring out your dead!"

There's a scene in "Monty Python and the Holy Grail" where, in the midst of an outbreak of the plague, a town crier walks alongside a cart loaded with bodies and repeatedly hollers for residents to "bring out your dead!"

"I'm not dead!" protests one still-very-much-alive individual readied for the pile. "I don't want to go on the cart!"

And so it goes with the Grateful Dead. The tie-dyed legends bid adieu with a series of "Fare Thee Well" concerts in Chicago this July, only to find new life with Dead & Company, which features Dead guitarist Bob Weir, as well as drummers Bill Kreutzmann and Mickey Hart. Into the fold the trio invited guitarist John Mayer, most recently spotted dressing like an extra from director Quentin Tarantino's forthcoming "The Hateful Eight" on the cover of his 2013 album Paradise Valley, Allman Brothers' bassist Oteil Burbridge and keyboardist Jeff Chimenti of RatDog.

Expect the assemblage to embrace the Dead's improvisational spirit - "We are going to blast our way into some serious drums and space," Kreutzmann said in a press release - which should suit Mayer just fine. Though best known as a solo artist, the guitarist has developed some unexpectedly sharp group chops playing alongside bassist Pino Palladino and drummer Steve Jordan in the John Mayer Trio - skills that will certainly come in handy here.
