The Mahwah Museum in Bergen County will host a night of Les Paul music June 7 at Ramapo College. Paul, the longtime guitarist-luthier-composer-inventor, who lived in Mahwah for many years with wife/duet partner Mary Ford, pioneered the solid-body electric guitar. He also pioneered overdubbing, tape-delay and multi-track recording. “The 110^th Birthday Celebration Concert,” from 2:00 to 5:00 p.m., will take place at Ramapo College of New Jersey’s H-Wing Auditorium, 505 Ramapo Valley Road in Mahwah.
