Burlington’s Sound of Music Festival has added two more acts to its June 13 one-day, one-stage ticketed kick-off concert event.

Collective Soul and Scott Helman have most recently been added to the live show which already included Weezer, Our Lady Peace, Finger Eleven and Current Swell.

Tickets to the 3-11 p.m. concert on the TD Stage in Spencer Smith Park on Burlington’s waterfront cost $60 plus fees and taxes.

Proceeds from the ticketed concert go to keeping the Sound of Music Father’s Day weekend festivities free. This year’s lineup for the free June 18-21 music festival will be announced Friday, May 8.
