Rock City Café, 316 Main St., will present Giff Jamison and Nancy Sferra Friday, June 16, from 7 to 9 p.m. On Saturday, June 17, Rock City will host a summer solstice seisún during the same hours.

Originally from Minnesota and now a Maine-based songwriter and performer, Jamison draws from folk, jazz and rock influences, but his roots are country blues and finger-style guitar. He is a four-time finalist at the New England Songwriters Contest; and has released a CD of original tunes, 2013’s “Ramone.” He is regular performer along the Midcoast, playing as a solo artist and in the company of fellow songwriters and musicians.

The Midcoast’s Sferra is a multi-instrumentalist who got her musical start teaching herself to play guitar on a nylon string Harmony (purchased with S & H Green Stamps) and moved into songwriting. With the new millennium, she began performing her folk-blues compositions locally and recording. At the same time, she ventured into learning new instruments such as lap steel, banjo, ukulele, banjo-ukulele and washboard.

Saturday night’s traditional Irish session invites one and all to join local musicians for an informal evening of traditional Irish tunes and a few songs. It’s a vast repertoire; in a session, musicians come together to play the tunes they know in common and see what comes from their musical "conversation."

Food is available until closing. For more information on these and other events happening at the coffeebar/cafe, call 594-4123 or find it on Facebook.
