A 40+ year festival tradition returns when Clark Park holds its annual Music and Art Festival in the Dog Bowl today, and this is also the year it returns to being a two-part Summer Solstice and Fall Equinox event. The fest will feature its usual plethora of craft vendors, food trucks, and family activities that start with a special performance by the Rock to the Future band, but at the center of the festival is a diverse lineup of 10 musical acts. Co-headliners City Rain will be bringing their vibrant soundscapes that radiate from the duo’s latest album, Songs for a High School Dance, and "golden age" indie rockers Commonwealth Choir will deliver a pumped-up set, fueled by songs from their noteworthy debut EP Shirtless. Saturday will be a good opportunity for charismatic Toy Soldiers frontman Ron Gallo to preview songs from his forthcoming album project Ronny, and you’ll find the whimsical folk collaboration of Dani Mari and Reverend TJ McGlinchey that’s known as Lovers League. The fest will also feature performances by Former Belle, Portland Senator, Family Vacation, and more. Clark Park, 43rd & Chester Ave., 12pm, FREE, All Ages – Bill McThrill
