Headlining this week is Cincinnati’s Seabird, a piano-driven Pop/Rock band that has had success with a pair of albums for EMI/Credential Recordings. As a special little World Choir Games tie-in, the group — currently working on a new Kickstarter-assisted full-length — will be joined during its set by the award-winning Boğaziçi Jazz Choir from Turkey. Also on Friday’s bill are great Cincy rockers The Harlequins and Chicago Indie Folk ensemble Jon Drake and The Shakes. Friday, July 13. Showtime is 7 p.m. myfountainsquare.com.
