A great event poster can be so mesmerizing, it's tempting to put it on your wall regardless of what performer it represents, even if it means Sheryl Crow becomes your favorite mistake. For a poster site that puts artists first, hit Poster Cabaret
Founded by a UT grad, Cabaret's a constantly updated online warehouse of 2000+ concert-and-more posters & prints; instead of giving prominence to performers/events, everything's organized by the site's 75 contributing artists, incidentally the same number it takes to screw in a "this is not a lightbulb". New arrivals range from WA-based Invisible Creatures' Conan O'Brian tour poster depicting a monkey sitting in a jacked up coup, to Oakland's Small Stakes' pair of birds caged inside an acoustic guitar (for Flight of the Conchords), to Justin Hampton's meta Pearl Jam poster featuring two vintage delinquents wheat-pasting their own flyer onto a fence, though if there's one thing kids aren't on the fence about, it's not knowing who Eddie Veder is. Sometimes the artists do join forces on a theme, as when 16 of them cranked out designs for National Bike Month, including 4-color monsters riding a triple tandem by ATX's Vahalla Studios, a tracered-out depiction of a bike light from Minneapolis' Landland, and Sonnenzimmer's "In Search of Cromwell Dixon", an ode to the aeronautical pioneer who plunged to his death on a bicycle-powered dirigible (lesson: if you want to bike, skip the Blimpies)
Some of Cabaret's work isn't tied to bands or events at all, as with Methane Studio's skull composed of browning leaves, and Perricone Design's colorful listing of the 50+ ingredients in a Hot Pocket -- specifically ham & cheese, though Hot Pockets are so mesmerizing, it's tempting to put them in your mouth regardless of what meat they represent.
