The Hall of Fame singer-songwriter (“Take It Easy,” “Running On Empty,” “The Pretender”) and intrepid political activist, still kind of a dreamboat at 70, plays an intimate acoustic concert (with singalong!), accompanied by legendary guitar and steel guitar player Greg Leisz and singers Alethea Mills & Chavonne Stewart. 8 p.m., Ruth Eckerd.

Jackson Harpe Collective. Harpe (along with Mike Cornette) is one of two jazz hosts on WUSF with musical surnames. He’s also an accomplished musician, a trumpeter with his own combo. He returns to the Studio@620 with a program of jazz, funk and original music inspired by the movies. 7 p.m., Studio@620.

Limelight: Michio Kaku. Tampa Theatre’s speaker series continues with the renowned futurist and theoretical physicist. 7:30 p.m., Tampa Theatre.
