To all Brandeis students who were not present at the K Records show at Chum's Sunday: You made the wrong choice. The free concert, staged by the Punk, Rock 'n' Roll Club, attracted about 150 people who left having witnessed two phenomenal sets.Phil Elvrum's and Karl Blau's meandering, somewhat solipsistic performances -culminating in an impromptu sing-a-long led by Elvrum-were transcendent. Both sang short, barefoot, acoustic songs laced with non sequiturs and quiet percussion wedged in between chords and spontaneous hand gestures. Although their performances seemed unrehearsed and, at times, completely improvised, Elvrum and Blau, along with Bret Lunsford-the third member of D+, which opened the night-were remarkably tight after sometimes suffering false starts and early missteps.

Some of the most popular performances of the evening involved Blau's use of a loop machine to combine beatboxing, electric bass and vocals, allowing him to double track his vocals on stage. The low fidelity of the machine blended the recorded samples into a percussive hum that complemented Blau's Beck-like faux-rap vocals. The main attraction of the evening, however, was headliner Phil Elvrum, as Mount Eerie. Elvrum's brief still-lifes ended abruptly, leaving the audience in a state of quiet inertia until the next song-or until his slightly awkward but entirely charming banter interrupted the post-song applause.

Calvin Johnson, who founded K Records but who is probably best known for his part in 1980s indie-rock band Beat Happening, also performed. While making use of the meandering, insular style of the other performers, Johnson's songs had an ironic, oddly humorous edge to them that Elvrum's and Blau's lacked. Johnson plodded tunelessly and often chordlessly through folkish ballads in a voice like Stephin Merritt's, devoid of any sincerity. Fortunately, much of Johnson's lyrics consisted of David Berman-like wordplay that was compelling enough to keep the audience laughing hesitantly throughout his set.

It must be noted that the filler between sets -an album of remixes of Mirah, a labelmate of Elvrum's who collaborated with him on his previous project, The Microphones-was entirely appropriate to the show and made the breaks between sets all the more enjoyable.
