The monthly Folk Jam/Song: Circle/Sing-Along affords musicians and singers of all experience levels an opportunity to play, sing and hone their performance skills. On the third Sunday, August 21, 2-4 p.m. one Sunday a month in Palmas del Mar, Humacao the Folk Jams are completely acoustic, unplugged events attended primarily by amateur musicians and those who love to sing. The first half hour is dedicated to ukuleles. These free lessons will let you play along with others. Song selections range across the broad folk milieu. To get us started, the theme for this session is a throwback to Bob Dylan, Peter Paul and Mary, the Seekers, Old Crow Medicine Show. Participants are asked to bring their voices, acoustic instruments, and a snack/non-alcoholic beverage to share.
