Singer-songwriter Zach has been playing in Northeast Ohio for 15 years now. His soulful voice and positive attitude have made him into a real catalyst on the scene. On his new album, Provenance, he collaborates with local artists such as Brent Kirby, Kristine Jackson and Colin John. Yesterday, he came by our offices and brought Charlie Mosbrook and Rachel Roberts, two of his musical friends who appear on the album, to play a few songs from the disc. Zach's next big gig: he opens for Red Sun Rising on Friday, Aug. 30 at Rockin' on the River. Proceeds from album sales go to local anti-violence charities. The disc can be purchased here.
