Like many things, the cinematic soundscape that Shearwater create pay heavy rewards to the patient, attentative listener. Founded in 1999 by Jonathan Meiburg and Will Sheff of Okkervil River, Shearwater was initially designed to merely be an outlet to share quieter songs that the two were working on. But after putting together five full-length albums, including 2006's critically acclaimed Palo Santo and the brilliant follow-up Rook, Shearwater are now a main attraction. See them on Thursday night at Mohawk with Wye Oak and Jennifer O'Conner.
