The members of Furious Bongos, a tribute act to the late, great Frank Zappa, have some serious musical credentials. A self-proclaimed “freak of nature,” drummer Filip Fjellstrom can play just about anything, including a toilet seat. Keyboardist Kevin Bents toured with Frank Zappa’s son Dweezil Zappa and worked as Jewel’s musical director at the height of her career. Bassist and band leader Conrad St. Clair has worked with people like Mick Fleetwood and Yo Yo Ma, and singer Jenna Paulus has a Master's from Boston Conservatory. The band comes to the Beachland tonight at 8. The group is shifting its annual schedule, and this will reportedly be your only shot at seeing it play this year.
