It’s been a busy few days for guitarist John Mayer! The festivities began last Friday, when Mayer made his debut as a special guest of Joe Russo’s Almost Dead at the Brooklyn Bowl in New York, NY. Watch here. Not only did the guitarist play a full set with Almost Dead, but he stayed in the Big Apple and joined Alicia Keys during her surprise performance in NYC’s Times Square on Sunday night.

The guitarist must have immediately jumped on a flight to Los Angeles, because he was spotted at a Bob Weir concert at the famed Wiltern Theatre last night. Weir has been on the road supporting his new release Blue Mountain, treating fans to a selection of new cowboy-themed originals and classics from the Grateful Dead catalog. As Mayer had been playing said classics all summer long with Dead & Company, his appearance last night was a real treat for those in attendance.

Mayer emerged during the second set, lending a hand on a rockin’ version of “Jack Straw.” The sit in marked three consecutive surprise appearances from Mayer in four days, as well as the first time that Mayer and Steve Kimock have shared the stage. Mayer continued on to play “Morning Dew” and “I Know You Rider,” with Matt Berninger of The National emerging to sing vocals on the two songs.

After “Rider” ended the second set, Bob Weir returned and performed a solo acoustic rendition of “Ki-Yi Bossie” from his new album. He then welcomed back his entire band, as well as Mayer and Berninger, to close out the show with two more beautiful songs: “Peggy-O” and “Ripple.”

Watch some of the musical magic below.
