Each season at the Levitt Pavilion offers free live music for a rainbow of musical tastes and possibilities to fall in love with your next new favorite genre or artist, and this weekend’s concert lineup is no exception.  On Friday night, kick back and let your hair down with indie folk tunes headlined by “enrapturing” Nashville-based Seryn; local folkers Mountain Natives will open. Saturday night, switch to Latin rhythms with the soulful Carlos Ramos followed by Grammy winning headliner La Santa Cecilia. (Pro Tip: Arrive early on Saturday and stroll the nearby West Main Arts Festival, open noon to 8 p.m. and featuring original wares from more than 100 artists and makers.) More free music will happen on the Levitt lawn on Sunday night, and no matter what evening you visit: Lawn chairs are encouraged, picnic baskets are welcome, food truck fare is available, and no tickets are required!
