Knock on Wood, acoustic foklk-rock duo

Howie Newman and Joe Kessler, also known as Knock on Wood, are anything but a typical folk combo, performing well-known rock covers and a few funny original songs (suitable for all ages). Their varied repertoire includes everything from Tom Petty to the Eagles to the Beatles. No matter what they play, it features excellent musicianship, pleasing vocal harmonies and … lots of fun.

Knock on Wood (howienewman.com/knockonwood) will be playing a free outdoor concert at the Westhampton Public Library, 1 North Rd., on Friday, Aug. 22, from 6-8 p.m. If it rains, the show will be held at Town Hall.
