From Power Trio To Duo To Single

Rock has seen a lot of different group variations, from the quintet to the quartet to the power trio to duos like The White Stripes and The Black Keys. John Marek does the power duo thing one better by playing both guitar and drums at the same time while singing, and doing a pretty good job of it too. Paul McCartney famously played all the instruments on several of his hit albums, but I bet he never did it at the same time, like John.
