The tiny, picturesque city of Niwot, situated near Longmont and Erie in Boulder County, is as well known for Chief Niwot's Curse as for anything else: Legend has it that the chief puts a curse on any resident of the city who tries to relocate. Fortunately, those who stick around out of fear have a great little jazz festival to keep them occupied. Jazz on 2nd Avenue takes over the main strip in town, and last year's lineup included Liquid Soul and Jeff Coffin of the Dave Matthews Band. Sure, some local and school bands play, too, but the musical quality on display is still exemplary. Taking place in September, when the weather is nice but not stifling, Jazz on 2nd Ave is Niwot's crazy little secret.
