This weekend is the Berklee Beantown Jazz Festival. The main event is the free, outdoor festival on Saturday, from 12-6 p.m. They'll have three stages set up on Columbus Avenue, between between Mass Ave and Burke St. in the South End. Check out the
performers and schedule. Best way to get there is bike or the Mass Ave. T stop on the Orange line. Great place to hear some great music!
Other concerts, big and small, are scheduled around the main festival. More info
