Philadelphia-based singer-songwriter Jake Brennan, a Queen City expat, recently unveiled a new album under his Violet Ultraviolet moniker. Titled As the World Churns, the eight doleful tracks recall the loose, carefree vibes of ’70s acoustic rock. His tunes tread into slightly twangy territory, especially on his cover of Tom Petty’s “Time to Move On.” In some ways a bit more raw than his 2016 Section Sign Records release, Pop City, the new album retains the artist’s candid sentiments and pastel imagery. Violet Ultraviolet performs on Saturday, June 29, at the Monkey House in Winooski. Locals Paper Castles and Dead Island also perform.
