Jason Gregg has 4 The Black Keys concerts.

The Black Keys is a two-man blues-rock group from Akron, Ohio, United States which formed in 2001, consisting of singer and guitarist Dan Auerbach and drummer Patrick Carney. The band name was inspired by a schizophrenic artist and friend in Akron, who used the term "black keys" to describe things he disliked or people he did not trust. The Black Keys have roots in traditional blues and psychedelic rock stylings.
