While there wasn't any official announcement of the closure, all of the signs point to the bar being closed. They had a GoFundMe with hopes of raising $7,000 that has been taken down. Their website and Facebook Page are down and their phone number is no longer in service. I also emailed owner Tamika about the bar being closed, but received no response.
Back Beat Piano Bar is the first bar of season four (4th set) of Bar Rescue to close and the Bar Rescue Update Page has been updated with that information
