Delta blues are on tap at the Grass Shack Cafe tonight when steel guitarist Pete Herzog hosts the Ashland Blues Society’s acoustic jam.

It’s the first of what the group hopes will be regular informal jams with just as much heart but without the electric blast. The jam runs from 6 to 9 p.m. at 2045 Fern Valley Road, Phoenix.

Admission is free. See www.ashlandblues.org.
