It's the All Day Free Fest, which wraps up the Folklife Festival. Music starts at 10:45 a.m. and happens simultaneously between the big stage in the Amphitheatre and the street stage. You'll hear music from Absynth Quartet, The Trouble, Safari Boots, La Patina Band, Melanie Barnett, Vanishing Pints and many others. Bring some sunscreen. At 12:30 p.m. today, a three-day musical series commemorates and celebrates the "50th Anniversary of the Ascension of Saint John Coltrane." It's hard to believe we lost a giant of a musical force, and a man who would forever shape the future sound of jazz and the saxophone, 50 years ago. These aren't exactly tribute concerts per se, nor will you only be hearing songs from Coltrane's catalogue, but rather you'll hear local musicians paying tribute to the spirit and the sound of the man. Today you'll hear from Val Leone on guitar, Ricardo Cueva on bass, Lucas Condeni on drums, John Labno on harmonica and Don Baraka on the saxophones and flute. Find them today for free at Cafe Phoenix in Arcata. Feel free to get ready for these three days of tribute by listening to Trane himself. Blue Trane, A Love Supreme, Stardust — you can't go wrong. Some original surf rock is on the bill at the Mad River Brewery Tap Room at 6 p.m. this evening courtesy of Band O' Loko, who'll be doing the free thing for you and the family. Tip to help 'em out. Down the way in Blue Lake are The Undercovers, who are stopping by the Blue Lake Casino and Hotel's Wave Lounge at 9 p.m. You'll hear covers from the past few decades, and I bet you'll recognize almost all of them. It's a free show, so head on over. If you missed Steel Rose last night, it looks like they'll be making another appearance at the Bear River Casino and Hotel. Same time, same place, same price. 9 p.m. and free.
