Alex Yaker is one of those way-busy Philadelphia musicians. Most recently, you’ve probably seen him rock his bass-playing swagger in Summer Fiction. In the past he’s performed with Grammar Debate, The Yaker Bros and done a bit of production with Surreal Sound Studios. With everything going on, it’s not unsurprising that his own project, Roomtone, only makes periodic appearances, but whenever it emerges, it’s worth the wait. This weekend, the band Yaker also refers to as “The Official Indie BossaNova Goosebump Machine” plays its first show in over a year and a half at Johnny Brenda’s, and best of all, they’ve got new material in tow. Snag a download below in this week’s Philly Local Phile, the buoyant new “Your Golden Crown.” Roomtone plays Sun. Feb. 12 at Johnny Brenda’s with Honeychurch and The Explorers Club. Tickets to the 21+ show are $10.
