Northern Spark Festival

The annual arts all-nighter returns Saturday with more than 70 artists and performers lighting up the sky and gettin' you lit (with light, that is). Spaces along the Green Line, the light rail that connects Minneapolis and St. Paul, will be illuminated by art projects — including a full-color wrap on one train, "Water Is Life," by Andrea Carlson, showing an American Indian water spirit and thunderbird. The theme is "Climate Chaos/People Rising." The festival follows the sun, beginning at exactly 8:59 p.m. (sunset) and ending at 5:26 a.m. (sunrise), preceded by a launch party featuring hip-hop group ZuluZuluu. A good reason to stay up late and not regret it. Info at
