A longtime presence on Cali’s underappreciated reggae scene, Rankin Scroo was introduced to a whole new audience through his work with E-40. That explains why Solid’s opening number, “Run Come,” doesn’t just bubble, it slaps. A one-man band, Scroo plays most of the instruments, sings and chats with equal finesse, and produced and mixed the album to boot. His self-determination is as evident as his talent, yet he’s not completely on his own: Ginger nices up “Heavenly Father,” Jah Dan appears on “My People,” and Lutan Fyah shares lead vox on “Dream Dream.” With contemporary reggae mired in a formulaic pop-oriented state, Solid blazes an original, independent trail through the roots-dancehall wilderness.
