Burlington landmark restaurant/music venue Nectar’s is going to close for a few weeks to remodel following the Jennifer Hartswick show tomorrow night. Nectar Rorris founded the club in 1975 and owned it through last year, offering gravy fries and appearing on the cover of a Phish album along the way. The current owners will now make Club Metronome part of the Nectar’s in order to present two floors of music. As for Hartswick, her band has confirmed a new batch of summer tour dates that will carry the group out to the High Sierra Music Festival on July 3.
