"Christopher Layer’s roots are here in Indiana; he’s the son of fiddle great Edwin Layer and soprano Dolores Layer. But Layer’s mastery of the Irish pipes — Uilleann, Scottish smallpipes and the Irish flute — have brought him international recognition and resulted in three, highly successful CDs recorded with harpist Martha Warren. Layer is on a solo tour of North America and will perform Oct. 10 at Radio Radio, 1119 Prospect St., at 8 p.m. Admission is free but a $10 donation at the door is suggested. You must be 21 or older to attend. "
