We think we might know who the hardest working music lovers in Kansas City are: the folks putting together the showcase for Kansas City talent at 2011's South by Southwest Music Festival. The showcase is called MidCoast Takeover. Following a string of fundraisers, a Kickstarter site and a free advance album, the organizers have assembled this last benefit show in Kansas City for a final push across the financial finish line. The goal: Raise enough money for a collection of local acts to rock a two-day local-music showcase in Austin, Texas. The bill: some of the city's most beloved groups, including the pop-country starlets of the Grisly Hand and the funk extraordinaires who make up Hearts of Darkness. Also taking the stage: Expassionates, Approach, Audiovox, and Everyday/Everynight. It's the last chance to help the scene take Austin by aural storm, so grab your dancing shoes and $10 and get down to Crosstown Station for the local love affair.
