While October 16th is undoubtedly Bob Weir‘s day in the world of the Dead, he’s not the only member of his current band celebrating today: today is also John Mayer‘s 42nd birthday!

The singer, guitarist, songwriter, and current Dead & Company member has come a long way since releasing his debut record, Room for Squares, way back in 2001. He started out as a young pop star, transformed himself into an expert blues guitar player with the John Mayer Trio, caught the attention of all-time greats like Eric Clapton and Herbie Hancock, and finally embraced his improvisational side when he joined Bob WeirBill KreutzmannMickey HartJeff Chimenti, and Oteil Burbridge in Dead & Co.

Over the four years since the band’s inception, Mayer has made leaps and bounds maturing in his new role “playing in the band” (vs. his background as a frontman), winning over countless notoriously critical Deadheads. We’ve seen him party down in a unicorn onesie at a Phish show in Las Vegas, sit in with acts like Joe Russo‘s Almost Dead on multiple occasions, and generally embrace the jam scene with the sincerity and humility that many decried him for lacking in his earlier years. If you need proof, just read this heartfelt note he posted following his U.S. tour this past summer:

This was the tour where all the pieces fell into place. The first tour without an album behind it, and a giant leap of faith that these songs could still matter after their time as chart contenders. You came, and you sang, and danced and wiped away tears and took inventory of what you had and what you’d lost, and all that’s left to discover, and I was thinking the same things right along with you, every night. Dead and Company taught me the “we” of you and me. The “we” of a band. This most excellent, loving band. “We used to play for silver, now we play for life.” We’re off to Europe to play some very exciting shows soon, but not before thinking back on what – and who – you’ve shown to me. Thank you.

If you’ve been listening over the last few years, it’s clear that John Mayer at 42 is quite different from the John Mayer the world met way back around the turn of the century. Take a look below at a few videos that show John Mayer progressing as a player and Grateful Dead fan over the years.

First up, check out John Mayer with his single “No Such Thing” from his debut record, Room For Squares, and remind yourself where he started out. Then, watch a full set by the John Mayer Trio performing at Bowery Ballroom back in 2005—a video that starts with an introductory interview which explains why Mayer is experimenting with new styles outside of the realm of pop music.

Next up, watch him perform “Human Nature” at Michael Jackson‘s funeral, filling in for Jackson by performing the vocal part on his guitar. Also included are videos of Mayer performing “Vultures” with the Trio back in 2010 at the Nokia Theater in Los Angeles and a performance of “High Time We Went” with Eric Clapton, Doyle Bramhall IIDerek Trucks, and Jimmy Vaughan, and a video of him playing the blues with Trucks, BB KingSusan Tedeschi and more in 2012.

While it’s clear that Mayer has always been a prolific guitarist, only recently was he “turned on” by the Grateful Dead music. That shift seemed to happen sometime in the early 2010s. As Mayer tells it, that switch first flipped when “Althea” popped up on a Pandora playlist at a pool party, prompting him to drop what he was doing and run to find out what the song was. By 2013, “Althea” had worked its way into his solo band repertoire, as you can see from the video of his well-executed rendition at Red Rocks that year. Just a couple years later, and John Mayer would be hosting a public jam session on late-night TV with Grateful Dead guitarist/vocalist.

Then, watch Mayer leading Dead & Company at Madison Square Square Garden in 2017, with a final video of Mayer in a full performance from Dead & Company’s 2018 tour (showcasing the impressive strides that he’s made in his Grateful new role) and a cover of “Deal” from his solo stop at MSG in July that shows how his Dead love has seeped into all aspects of his life and music.
