This really was fun, especially if you are like me, living in San Francisco. Interesting to think about which sidewalks might have hosted Jack in the past--maybe we should make a plaque! But I digress. Jack is a solo acoustic guitarist with a top drawer busker vibe. He folds at least one found song, from another busker in New York, which gives the album a good backstory. Had to listen on YouTube, since it's not on Spotify yet. It was on the border of three and four, but the Woodie Guthrie cameo bumped me to four.
