I'm fascinated by the two-member band. It seems bold to take on the bare minimum number of musicians that can technically call themselves a band and make a go of it.

Obviously, you've got your Jack and Meg White. Just a few days ago, Matt & Kim managed to keep CD101 Summerfest bouncing and bubbly all by their adorable selves. And you've got one of the most successful Ohio-grown bands of the past decade, Akron's The Black Keys.

A sweaty and ready crowd packed the LC Pavilion lawn for a sold-out show Friday night, and the Keys showed that, in the immortal words of Rob Base, it takes two to make a thing go right.

Singer-guitarist Dan Auerbach and drummer Patrick Carney got a little assistance, joined by two more musicians for a middle chunk of the set heavy on tunes from their latest album, Brothers. As it turns out, they don't really need the help.

There was something about the sticky, almost Southern, feel of the night that was oddly perfect for slinky, bluesy rock the duo has perfected. Auerbach's fuzzed out guitar tones hung perfectly in the humidity. And dude's overworking fret hand brings memories of Hendrix.

Highlights included a growling and sexy "Your Touch" actually the whole set was kind of sultry in that heat my new favorite ex-kiss-off song "Next Girl," and and effortlessly awesome take on the band's biggest hit, "I Got Mine."

The only drawback was a short and sweet encore and a show that wrapped up at just 10:30 p.m. I could have kept watching this band well into the hot Columbus night.
