Me too. DSO sounds more like the Grateful Dead than does D&C - even the vocalists sound a bit like Jerry, Bob, and Brent. I like John Mayer's guitar playing, but I'm not a fan of his voice. They should let Oteil sing all the Jerry songs, not just one or two ballads. They should also let him set the tempo, but I get the feeling Bobby can't keep up anymore.
I love how JRAD doesn't try to sound like the Dead - they put their own spin on the tunes. We had tickets to see them in March of 2020, but Covid interfered. It's rescheduled for this August and we're fully vaxxed, so I'm pretty sure we'll be there.
