Jack Johnson and Lake Street Dive perform a co-headlining concert at the iTHINK Financial Amphitheatre in West Palm Beach. The show pairs Johnson’s mellow, surf-influenced singer-songwriter material with Lake Street Dive’s energetic, soul-tinged indie-pop for a mix of laid-back folk-rock and upbeat pop-soul in an open-air amphitheatre setting. It is notable as a high-profile pairing of two well-established acts that appeal to adult-alternative and mainstream audiences.
