JamBase is celebrating their 20th year this June with a special concert at The Chapel in San Francisco.

The gig will feature performances by Big Light and Ron Artis II & The Truth, as well as The Camp Harry All-Stars, which promises a number of unannounced special guests.

“We’re excited not only to host this concert featuring some of JamBase’s favorite musicians from the past two decades, but to also share throughout the year specially prepared retrospectives on the last 20 years of going to see live music,” the concert-listing/news site said in an official announcement. “Stay tuned for more JB20 features and celebratory content throughout 2019.”
