Cut past the nerdy hipster schtick, and - if you're not trying to DIY - the technical orientation. Starting at 5:20, these guys bust a surprisingly palatable mashup of Prince, Vampire Weekend, G'N'R, Eurythmics and... I Dream of Jeannie.
We've seen other iPad DJs, and God knows we're going to see a lot more, in every style. But I like how this duo explains the main point of their novelty twist: To go wireless, and do their mixin' away from the computer. As one of the Andrews so cogently puts it, "I don't think you could ever do this with vinyl." Go ahead, try this at home. [Thanks Andrew Andrew!]
