Ad Hoc presents "Songs My Mum Used to Sing." Doesn't that just say it all? The minute someone with any English or Irish connection hears "Mum," we're taken into a small, cozy kitchen, potatoes peeling, and a Cadbury's biscuit jar to sneak into and get scolded. Ad Hoc's new artistic directors Boon Hua Lien and Matt Osika have scheduled a lovely concert, complete with selections from Benjamin Britten's "Folksong Arrangements" (with texts of the British Isles and W.B. Yeats) and "Lincolnshire Posy" by Percy Grainger.  Both works will feature wind/piano octet orchestration by Osika.

Ad Hoc performs Saturday, October 5 (7:30 p.m.) at Christ Church, 141 East Ave, $5, and again on Wednesday, October 23 (noon) at Hochstein School of Music & Dance, 50 North Plymouth Avenue, free (also airing live on WXXI's "Live from Hochstein" series), 474-2420, adhoc-music.org.
