The recent passing of legendary producer Tom Dowd returned the Hit Factory Criteria to the media spotlight, reminding us all that the North Miami studio was the creative birthing spot for so many seminal albums, from Derek and the Dominos' 1970 Laylaand Other Assorted Love Songs to the Bee Gees' 1977 Saturday Night Fever soundtrack to Bob Dylan's 1997 aesthetic return-to-form comeback Time Out of Mind. Yet what often gets overlooked is the appeal of the studio itself. Indeed it wasn't just Dowd's own production techniques that had drawn a musical who's who to work with him here. As important as the sounds being laid down on any session is the equipment being used to capture it -- and this studio's analog-style mixing boards, vintage microphones, and sumptuous wooden acoustics have artists from Christina Aguilera to DMX catching flights into Miami when it comes time to record. Accordingly, studio time at the Hit Factory Criteria is pricey, and a few weeks' worth of work can easily produce a hefty six-figure bill; this isn't the spot to cut your garage band's demo. But if you're on a major-label budget, the dizzyingly infatuated look engineers take on when gabbing about the equipment at hand seems justification enough for running up that tab.
