If Busses new 2-track EP Metal/Shangri-La is an indicator of the trio’s desired sound, then they may be on to something. The first half “Metal” begins with a guitar that gradually increases in decibel as if first heard faintly approaching in the distance, creating the lure of anticipation. Moments later, it arrives with a bang as drums kick the track into gear. When the lead vocal finally enters the equation it seems to take control as a calming force. The opposing track works in reverse the vocal creating a peaceful comfortable setting that the other instruments play within rather than fitting through. In either case, the overall feel is well-produced by the band and Kyle “Slick” Johnson and refined with hints of being rough around the edges. They’ll be joined by Break It Up, whose sound combines the sweet vocals of modern pop with the grainy attitude of post punk, and Orbit to Leslie, whose interstellar journey finds them time-warping to the land of 50’s doo wop funneled through a hazy, psychedelic strainer.
