While Missoula-based Cosmic Sans may boast a whimsical name, the self-described “Western psych” five-piece brings big goals and professionalism to its craft. In late March, the five-piece will perform two sets at Boise’s Treefort Festival, and in April the group will release its second full-length album, “Psychedelicatessen,” via the small Missoula label Drag Bunt Records.
