Any long-time fans of Chris Robinson's main band, The Black Crowes, knows the man like to have a bit of a jam now and again. With this band, the Chris Robinson Brotherhood, the lanky singer and guitarist gets to stretch out plenty with the cohorts Neal Casal, Adam Macdougall, George Sluppick and Mark Dutton. The band's latest album, Phosphorescent Harvest, packs 10 songs with a lot of twists, turns and exciting connections between the musicians on hand. Robinson's soulful vocals ring through, though, and the band's blend of psychedelia and rootsy rock should make for a popular attraction at the Utah Arts Festival Friday night. You'll want to be sure to explore the festival's entire music lineup--there is plenty of national and local music well worth your while this year, including Angelique Kidjo and MarchFourth Marching Band, as well as locals the Hollering Pines and Zodiac Empire. On Saturday, Robinson's crew will headline a sold-out show of two sets at The State Room. It might be tough to get a ticket, but it will be a memorable show to be sure.
