Worcester’s Brew Beer Garden is opening the latest addition to its space on Franklin Street — a 300-person, four-season Pavilion — Tuesday night with a performance by XS Band.

The venue, located at 64 Franklin St. in downtown Worcester, is already home to an indoor beer garden and outdoor terrace. The addition features a 300-person standing capacity, 28-foot stage, full sound and lights and a 19-foot LED video wall.

The Pavilion opens to the public Tuesday at 8 p.m.

It adjoins the Beer Garden on Franklin Street, which has 36 beers on tap, a full dining menu, an outdoor terrace and indoor live entertainment.

The Pavilion will feature ticketed national concerts, local showcases and space for weddings and other events.

This week’s lineup includes Boston’s DJ Sisko on Thursday; DeadBeat — a Grateful Dead tribute band — on Friday; and a variety of bands followed by DJ TecThreat during an all-day grand opening event on Saturday.

Sunday will feature Boston Beautease — a summer-themed burlesque show.
