Charlie Marie
7:30 p.m. Friday. Behind the Grant Building, 31 Centre St., Bath, $12, free for kids under 12. Grant Lot Summer Outdoor Concert Series on eventbrite.com.
Rhode Island’s Charlie Marie will be bringing her classic country sound to Maine for an outdoor show in Bath. She started her first band at 16 and released her debut full-length album “Ramble On” earlier this year. With original tunes like “Heard It Through the Red Wine,” “El Paso” and “40 Miles from Memphis,” Marie’s the real deal when it comes to vintage sounding music that honors traditional country yet carves its own path with her sensational vocals, songwriting and band.
