Regattabar, the jazz club in Harvard Square’s Charles Hotel, reopens Sept. 15, said Alex Attia, the Cambridge hotel’s general manager. The first act in the revived club is Blue Note recording artist and Berklee woodwinds department chair Walter Smith III, playing with a quintet.

The 220-seat venue on the hotel’s third floor closed March 17, 2020, for the Covid emergency and took longer than most to get up off the sickbed – teasing a return at the end of January, promising it April 1 and posting a call for new staff April 11.

With a team finally in place, “we look forward to once again offering our guests world-class musical experiences,“ Attia said. “Regattabar’s legacy is intertwined with the history of The Charles Hotel and invaluable to the Cambridge community.”

Originally opened in 1985, Regattabar has been awarded “Best of Boston” nine times by Boston Magazine. It features local talent – in a press release Thursday, Attia said Regattabar is partnering with JazzBoston, Sun Music and the Berklee Institute of Jazz and Gender Justice on a series with world-class musicians based in Boston.

There’s also a schedule of more widely known talent coming together. Grammy-nominated vocalist Gretchen Parlato and guitarist Lionel Loueke are set for Oct. 6; Los Angeles composer Bevan Manson, nine-time Grammy nominee Tierney Sutton and vibraphonist Joe Locke are on the calendar for Nov. 11.

Regattabar is at 1 Bennett St., Harvard Square, Cambridge.
