MIX 104.1’s annual free MIXFest concert is returning to Boston on Saturday, September 19th with a stacked lineup of live performances. As announced during the Morning Show with Karson & Kennedy with the help of Rob Thomas, former Matchbox Twenty front-man and MIXFest 2015 participant, this year’s roster will also include highly-anticipated appearances from the following artists: 90’s hit punk-rock band, Third Eye Blind; Massachusetts native breakthrough artist Rachel Platten; Australian indie-folk singer, Vance Joy; and soul-pop singer Andy Grammer.
 
In its 22nd year, MIX 104.1 will once again treat the Boston community to a FREE show at the DCR Memorial Hatch Shell along the Charles River rain or shine.
