This Mother’s Day, show her you care.  Nothing says “Thanks Mom” like a high-octane concert of Lachenmann, Ades, Nono, Alex Mincek, and Kyle Hillbrand.  And — just your luck — such a beast is roaring our way with David Hanlon’s Hold the Applause concert at Gallerie Icosahedron this Sunday at 5:30pm.  Of course, if you don’t love your Mom — or you live outside the Eastern timezone — your presence can be excused.  Otherwise, troops, forward march!  The various links will give you all the details you need.
