THOUGHTS: Joe Pug is a singer-songwriter whose folk music is as tender and moving as it comes. Performing solo, armed with just his acoustic guitar and a harmonica, Joe’s soothing sound, under the bright red spotlight, mellowed the audience into a blissful trance. His performance was emotional, without being overindulgent. Critics have favorably compared him to Bob Dylan, and I can’t disagree. I like Bob Dylan. I also like Joe Pug.
