Rob Thomas

Koka Booth AmphitheatreRock’s changing of the guard was complete when Carlos Santana had to hitch his wagon to Rob Thomas’ star for the duo’s 1999 chart-topper, “Smooth.” The former Matchbox Twenty singer, who landed on People magazine’s list of “Most Beautiful People,” also penned many of the band’s platinum hits before striking out on his own, making an about-face from post-grunge to dance-pop. Cradlesong is his latest offering. Gates open at 5. Girls start swooning at 6. Tickets are $36-$66. Visit Lisa Sorg
