ArtsQuest's four-day SteelJam festival featured over 45 music acts during Labor Day weekend. These photos are a sampling of the musicians from the Sunday of the festival. SteelJam included performances all day long in the Musikfest Cafe, on the JamBase Levitt Pavilion stage and on the Air Products Town Square. Sunday's headlining act on the JamBase Stage at the Levitt Pavilion SteelStacks was Umphrey's McGee. Keys N Krates turned up the volume at the Levitt Pavilion with their funky dubstep and breakbeat tunes driven by loud bass lines. ALO and From Good Homes took the stage in the Musikfest Cafe.
