The final show of the Washington Concert Association’s season is this evening. WCA President Linda Miksch says it will feature Canadian musician April Verch. Miksch says the performance will include a wide array of musical stylings. Miksch says they’ll be offering free admission to the concert with the purchase of a pass to the 2009-2010 season. She says if youre not sure if you want to commit to season tickets, you can still get in to the show for $15.
