Soul II Soul’s Jazzie B is mostly known for his U.K. R&B productions such as “Keep on Moving,” but dude is a serious reggae man, having run Jamaican-style sound systems for decades. School Days sees Jazzie comb through Trojan’s vaults for personal favorites, and his choices are superb. Alongside ‘70s roots numbers like Jacob Miller’s cannabis ode “Tired Fe Lick Weed in a Bush” and Gregory Isaacs “Slavemaster” (with I-Roy’s DJ version “Point Black” included) are proto-dancehall boomshots like Tenor Saw’s “Ring the Alarm” and Admiral Bailey’s lively King Jammy-produced “Jump Up.” Classic 12”-length tunes by Horace Andy and Barrington Levy share space with lovers fare by Dennis Brown and Alton Ellis. For this class assignment Jazzie gets perfect marks.
