Feverslip, an energetic group of young musicians from southern Maine, makes its first appearance at The Porch, joined by special guest Gold Star Blvd. Feverslip boasts a well-defined musical precept — keep rock music alive — and they do that with their own brand of modern roots-rock blues. Sam Vlasich handles lead vocals, with Jordon Brilliant on guitar, Harrison Foti on drums, Liv Lorusso on guitar, and Brad Hartwick on bass. Gold Star Blvd. is the central Massachusetts rockers David Dunne, Luke Maciorowski, Bryan Kant and Alex Kant. General admission tickets are $10 through Eventbrite.
