John Mayer is a seriously good guitar player! Good voice too, def. a modern talent. I know it's kind of soft-rock/new age and cringey, but "Gravity" gives me chills. I'm also a fan of some classic Dead stuff, but not the open jam-band and more the tighter albums like American Beauty but especially Workingman's Dead. That's a kickass album right there and my dad played it a lot growing up. Lots of tight ~3-5 minute tracks.
My (jazz) guitar player OTOH went to see Dead and Co. featuring John Mayer like 6 months before the pandemic hit, and reported that he had a good time. I considered going (Hollywood Bowl) but was busy that weekend.
