94/7 is sort of like the Jack in the Box of radio stations. Long ago, KNRK was characterized by “politically incorrect” DJs and rock blocks that consisted pretty much entirely of awful nu-metal. In an event analogous to the 1993 Jack in the Box E. coli outbreak, two KNRK DJs fucked up catastrophically and made fun of the Nick Berg beheading on air, resulting in their immediate termination and a hiatus. Shortly thereafter, it remerged as the sleek, relatively conservative 94/7 (similar to the introduction of the “Jack Box” mascot), and became Portland’s premier radio station for middling alternative rock. For two nights, 94/7 will be celebrating its 21st birthday at OMSI with performances from a number of middling alternative rock bands. The event is all ages, but somehow that doesn’t seem relevant when a single-day ticket costs $55—what kid can afford that? MORGAN TROPER
