If you don’t know it already, Richmond probably has the greatest Talking Heads cover band in the world. On Sunday, May 11 — that’s right, Mother’s Day — local band Fear of Music will be kicking off Music in the Park, the free Sunday night concert series that runs from 6 to 8 p.m. in Forest Hill Park. If you haven’t seen them, you should: Fronted by the husband-and-wife team of Nate and Chrissie Griffith, this group nails the hits and deeper cuts, and their funky, percussion-strong dance pop is infectious. They don’t sound like a tribute act. They sound like a party. Do it. And bring your moms.
