The Porch Southern Fare & Juke Joint at River’s Edge welcomes back Gnyus for a free show during dinner. Born Kevin A. Grace in Cambridge, Gnyus grew up in West Medford. Over the years starting at Brooks Elementary School he began to learn to play several musical instruments, beginning with the violin. Today he is a multi-instrumentalist who sifts through rock, funk and soul on his latest album, “Magnum Opus,” which crosses all genres and all walks of life. Music is free during dinner (make a reservation if you want a table) and admission is $10 after 9 p.m.
