Music Tonight: Minnesota-based sound artist Tim Kaiser is part musician, part inventor and part explorer. In turn, his appearance tonight at the Aisle gallery (on the third floor of 424 Findlay St., in the Brighton arts district) will be part exhibition, part performance, part electronics clinic, as Kaiser comes to town equipped with his unique, homemade instrumentation. He makes the art to make his art, as it were, constructing some 150 various contraptions (take a gander at several here) that help him manipulate the notation, frequencies, circuits, mood and atmospherics of his often ambient, always textural and adventurous music. As Kaiser put it in this interview with Nashville Avant Garde music website Theatre Intangible, his sonic creations are "like folk music during the Civil War. If you wanted a banjo, you built a banjo." The event begins at 8 p.m. Call 513-241-3403 for more info. Below is a clip of Kaiser showing off some of his creations.
