This was another of the SF City Guides Tours that was held in the last few weeks. It was well worth watching. It was about Big Brother and the Holding Company. They are apparently still touring, but they are currently online. www.musae.me/bbhc/experiences/809/vr is where you can get tickets. They start at $5 and go up for virtual shows.
The talk itself was interesting. It told about the history of the band and its members. It will be shown again, from what they have said. Find them at the link in the above photo. It’s well worth a visit.
