Some remarkable samples of last year's art are seen in the Kastner & Partners ads promoting the 2007 edition of Red Bull's Art of Can. The competition strives to be inclusive ? virtually anyone can enter, and, as Red Bull notes, it accepts works of art "in any medium: sculpture, collage, animation, a piece of furniture, perhaps, or even a song." The latter could be played on an aluminum glockenspiel, but in 2005, for instance, an entrant made an artsy film about all the sounds that can be made with a Red Bull can (click here for that). The 2007 festivities feature exhibitions in Philadelphia, Oct. 19-Nov. 2, and Chicago, Nov. 9-18, with roughly 40 entries to be selected for each showcase. The submissions deadline for Philadelphia is June 13; for Chicago, June 25. See RedBullArtofCanUSA.com for registration info and an astoundingly detailed array of previous Art of Can galleries.
