The occasional series of free performances in Camden Opera House’s intimate third-floor listening room welcomes Chris Ross back for a solo performance, after he opened for the Mallett Brothers this spring. The award-winning Maine singer-songwriter is a native of Hancock and past winner of the New England Music Awards’ Songwriter of the Year award. Known for his cinematic lyrics and sharp humor, Ross’ wit matches his musical talent. Elevator lobby doors at 29 Elm St. open 7 p.m. Free admission to all. Donations to the sponsoring Community Arts Fund are welcomed.
