As far as I know, the White Stripes were the premier group using this minimal configuration, and certainly my favorite in this genre was and is the Black Keys. Here are some interesting recent additions in no particular order:
Black Pistol Fire live on KEXP
Royal Blood who are interesting because they use a Bass guitar and drum. I don’t especially care for them, but haven’t heard much of their output.
Jeff the Brotherhood who use a small drum kit and often only 3 strings on the guitar and I think create a massive sound.
Update: Equal time for the ladies with The Pack A.D. from Vancouver, B.C.
