12. Eric Prydz, 'Opus'
Since his monster 2004 radio hit "Call On Me," Swedish producer Eric Prydz has veered away from those vocal-heavy, relentlessly upbeat, uptempo pop-house stylings, and instead has ventured into much headier and atmospheric territory. As his original material has delved into the nuanced worlds of progressive house (with touches of freshened-up trance) he's released it only shrewdly, with only one official single coming in as many calendar years. So this studio effort, only his second, feels aptly named. With 19 tracks unrolling for almost two hours, Prydz traverses gauzy, peak-hour anthems ("Generate"), Eighties-inflected slink ("Black Dyce," "Moody Mondays") and even some comedown-cool ("Sunset at Café Mambo"). The stunning final title track throws it all the way back to the days before trance became a bad word, full of synth washes and driving snares. At its best, Opus approaches the seamless, cinematic quality of a proper DJ set, seriously pulling nostalgia strings while providing contemporary big rooms, once more, with some feeling. A.C.
