Look closely at the most creative flyers touting the barrage of DJ events in Miami, and you're sure to spot the Plex credit. The firm is the creation of graphic-design team Steven Castro and Rick Garrido, who have done some gleefully twisted stuff. Less well-known is the appointment-only record store the duo operates out of their Lincoln Road office. The selection isn't voluminous but the accent is on quality, not quantity. They peddle vinyl that's truly underground (and otherwise impossible to find in this neck of the swamp), from off-kilter artists such as Detroit's neoelectro tweaker Ectomorph, Minneapolis idm creepy-crawler Jake Mandell, and Berlin's dubbed-out Chain Reaction crew.
