Guitarist Earl Bigelow, keyboardist Michael Chipman and percussionist Nancy Bigelow will play Monday, July 23, at All Souls Chapel as part of the Poland Spring Preservation Society’s summer concert series. Performing as the Big Chips Trio, the seasoned singers and musicians share strong vocals with rich harmonies blending on much of their original, as well as cover, tunes. They perform a range of music from old standards by Patsy Cline and Louis Armstrong to hits by James Taylor, the Beatles, Norah Jones and the Dixie Chicks. The Big Chips Trio is a favorite at Bath Heritage Days, Music on the Mall in Brunswick and the Kennebec Tavern on Sunday summer afternoons. Showtime is 7 p.m. Admission is $5, with proceeds going to support the work of the PSPS.
