Drummer/keyboardist Benjamin Weikel and vocalist/guitarist Brandon Summers took a four-year break between releasing 2008’s Keep Your Eyes Ahead and 2012 fifth album Negotiations, likely as much of this time spent recovering from the aftermath of a flooded studio/rehearsal space as it was writing new material. The Helio Sequence twosome eventually landed in new digs in an old industrial building and completely re-tooled their studio. Digital equipment was replaced with vintage and analog gear, which imbues Negotiations with a naturally warmer sound, while its sparse instrumentals and the spaces between melodies lends the songwriting of the Portland experimental alt rock duo a cooler, more airy timbre than previous efforts. CL Writer Scott Harrell called it “an accomplished, accessible and subtly engrossing listen,” and hopefully the duo’s live presentation will prove just as engaging. Warm up set by Shabazz Palaces, the alt hip-hop collective led by Ishmael Butler (aka Butterfly of Digable Planets).
