Get a glass of wine or can of beer at the refreshment counter then settle back in the comfy armchairs in the small upstairs performance space of this Mount Vernon townhouse. Located upstairs from the first floor music shop, An Die Musik Live! presents both local and national acts, all very good even if you've never heard of them before. The calendar, which is online, is jam-packed with jazz and classical performances, usually more mellow than toe-tapping. If it says a Peabody ensemble is playing, be sure to attend; students and graduates of the fine music academy are always first-rate. Shows tend to be short—about an hour. If the crowd is small, visitors to the first show may be asked to stick around for the second. An Die Musik is within walking distance of some pretty good restaurants; show your ticket stub for a discount. A list of participating artists is on the website.
