This two-CD set of early-1970s Bob Marley tracks recorded by the legendary Jamaican producer Lee Perry illustrates the huge difference the revolutionary reggae producer made to the band's sound. The polite ska rhythm of the '60s is gone, replaced by upfront rhythm guitar and bass and Carlton Barrett's exemplary one-drop reggae drumming, while Marley's vocals are tougher and more confident. Peter Tosh's vocal on "Go Tell It on the Mountain" has the authority of a Biblical prophet, and Perry impeccably captures the sheer weirdness of the spooky "Duppy Conqueror."

Sovereign dub techno producer Moritz von Oswald (Basic Channel, Rhythm & Sound) aligns with Max Loderbauer (Sun Electric, nsi.) and Sasu Ripatti (Vladislav Delay, Luomo), two of the most well-regarded figures in electronic music. The three make a slight diversion from the expected, forming a perfectly calibrated machine in which European techno subsumes Latin, African, and Jamaican sources, but also perfect for improvisation and live performance. Whether immersed in weightless locomotive propulsion or hanging in suspension, these four tracks, modestly titled "Pattern 1," "Pattern 2," "Pattern 3," and "Pattern 4," make for an alternately gliding and hovering massage for the brain. Percussionist Ripatti, trained as a jazz drummer, anchors the pieces with an assortment of ricocheting and clattering handmade instruments--wooden, metallic, even water-filled--that create an oddly soothing tension when matched with von Oswald and Loderbauer's synthesizer sequences, drones, and treatments. A gorgeous, succinct set that can be slotted between Weather Report's 1971 debut and Ricardo Villalobos' TH� AU HAREM D'ARCHIMEDE.
