JACK Quartet Around these parts, the Burlington Discover Jazz Festival is known as the gateway to summer. Normally, the annual 10-day event reaches nearly every square inch of downtown, with scores of nightclubs, bars and restaurants hosting music under the BDJF banner, not to mention venues such as the Flynn, Flynn Space, Waterfront Park and Church Street Marketplace. The jazz fest took a pandemic-induced hiatus last year and was replaced by a fully online alternative, the Burlington ReDiscover Jazz Festival. The virtual fest was a valiant effort under dismal circumstances, but there's nothing like the real thing. So Tuesday's announcement of the BDJF's return has us all doing the Snoopy dance.
