Spanning the globe and through several musical genres, Clean Equations are creating ambient shoegazey orchestrations of songwriter/engineer Michael Nyhan. The group is a musical collective that also hails from NYC and as far Melbourne, Australia, and has found its home base for creating enchanting melodies in Philly. Nyhan released a self-titled EP in 2009, and has been hard at work on his first full length People/Variables for the better part of the year. And he even had some help from the likes of seasoned guitarist Nero Catalano and songbird Dani Mari. It was released on August 31 through State Capito Recordsl. Tonight’s show at Johnny Brenda’s marks the special vinyl release party. Joining them will be soulful South Philly rockers and Carriage House alum, The Great Vibration, who have been most impressive in their own right since the release of Purple Stuff. Rounding out the lineup is the ever impressive West Philly ghoulish indie popsters Conversations with Enemies, whose debut album Nowhere, OK came out just last month, and they managed to pull double duty creating an exciting graphic novel.
