For some fanatics, MP3 collections of entire discographies have been lovingly passed from hand to hand for years. Record labels probably should have caught on earlier, but the past year and a half has seen a trio of MP3 box sets: legally dubious boxes dedicated to the compilation series Ultimate Breaks & Beats and Streetsounds Electro, and now this completely legit set. B-Boy Records: The Masterworks stuffs four CDs with everything the short-lived mid-'80s Bronx rap label ever put out, from obscure 12-inches to J.V.C. Force's classic "Strong Island" and Boogie Down Productions' classic debut, Criminal Minded, which in 1987 helped jump-start gangsta rap. That album should be required listening; the rest of The Masterworks is a lot iffier—though in their rough-and-ready way, a lot of these tracks offer nearly as illuminating a portrait of the genre's ungainly growing pains as it prepared to occupy the driver's seat of the next decade's pop.
The Masterworks isn't all great by any means, but there are a healthy number of head-turners among its many selections. A great playlist could be generated with the diss tracks alone: Not only did BDP feud with Queens' Juice Crew, veteran Kool Moe Dee is the target of both Spyder D's "Try to Bite Me Now" and Incredible Two's "Moe Dee Get Mad," while the sleeper B Girls Live & Kicking compilation contained within features the wonderfully named Five Star Moet's "Moet Gets Busy (Shanté Diss)," which goes after Roxanne Shanté with similar gusto. There's plenty of hackneyed, on-the-beat flow whose appeal will puzzle anyone who came of age post-Rakim, but it's still an intriguing history lesson, albeit one that requires some cherry-picking.
