Les Paul Mondays at Iridium. Les Paul: a guitar hero before there was guitar hero, forget that, before there were electric guitars (he invented one of the world’s first). His professional musicianship has lasted about twice as long as the average American’s career, and currently he has two gigs every Monday at the Iridium. A member of three Halls of Fame (Grammy, Rock and Roll, and National Inventors), he has made enormous contributions to music, and his live shows draw quite a crowd. Sets begin at 8 and 10 pm.
