If you'd been here the past three days you could have gone to the free Hardly Strictly Bluegrass concerts in GG Park.

Here's an article on it in today's Comical. Estimates were 500K attendees.
We went over on Friday afternoon for Jimmie Dale Gilmore/Butch Hancock and then Elvis Costello. It was a typical day for out here at the beach - breezy, overcast, and chill. The music was great, even with the interruptions of strafing runs by the Blue Angels (it is Fleet Week). But several of those were timed perfectly to go with some comments from the entertainers about the current US administration and their adventuresome ways.
Saturday and Sunday were clear, warm and sunny. You can't count on the weather to not change as you move around the city.
I went over yesterday for T. Bone Burnett and Elvis C, and it was pretty obvious they hadn't done much rehearsing (and even Elvis admitted they didn't do very well).
I did catch the North Mississippi Allstars before I left, and they were great. They seem to be another band that benefits from live concerts. Singing is really not their long suit, and the shorter pieces on the albums have too much of it. But live there was a lot more space for some smokin' hot guitar.
The only bluegrass I saw was the NMA guitarist playing electric washboard. He had it plugged into his guitar somehow and made a lot of interesting sounds that worked out pretty well.
I can't recommend much in the way of tourist stuff as I stay as far away from them as I can. But the new De Young museum in GG Park, the Asian Art museum at Civic Center, the MOMA at Yerba Buena in the south of Market area downtown, and the Palace of the Legion of Honor are all excellent museums. The Exploratorium is fun too.
cheers,
