The March 15 concert at Our Times Coffeehouse features a double bill of Joshua Garcia and Mark Wahl. Joshua Garcia is a folk singer-songwriter whose music and writing style draw from the influences of his musical heroes Woody Guthrie, Bob Dylan, and Johnny Cash. His strong baritone and wide-ranging blues style guitar work combine with a deadpan sense of humor. Mark Wahl is a singer-songwriter, guitarist and luthier. Mark’s songs are often poignant vignettes with powerful use of metaphor and simple, compelling melodies. His full-time passion is making and repairing fine guitars, and says, “When I need a break I play them and write songs. I’m a lucky guy.”
