Led by Tyler Asay, The Tisburys have a new EP, which they’ve titled Wax Nostalgic. Exuberant folk/Americana streams in loose, catchy bursts that hit a personal chord. Meshing a sense of the optimism that one often holds in memories and ideal hypotheticals, there’s a bright, bouncy tone that lifts one up but is countered by a sadness felt in real time. The Tisburys will be performing this evening upstairs at World Cafe Live, where they’ll be joined by The 40th Parallel and Solars.
