Packed with notable collaborations from Jack Johnson’s annual Kokua Festival in Hawaii, this collection boasts a who’s who of folk, reggae, and rock musicians cross-pollinating their unique talents. Ziggy Marley and ukulele great Paula Fuga unite Jamaican and Hawaiian culture on the tender plea “Cry Cry Cry.” Latin funk collective Ozomatli and G. Love get the dance party started with the playfully groovy “Mudfootball.” And when Willie Nelson, Ben Harper, and Johnson turn honky-tonk classic “Blue Eyes Crying in the Rain” into breezy tropical pop, you can practically feel the palm trees sway.
