About the Band

Single Jo is an alt-rock band originating in Pittsburgh, PA. Fronted by singer/songwriter Mark Jeffries, the group's sound epitomizes the melting pot of the rock'n roll genre: fierce, fuzzed growls of garage & blues-rock are infused with the delightfully strange, colorful warmth of new wave & alternative.

In late 2017, Jeffries, under the FLY. moniker, released his debut solo EP, “She Will Like the Science”, recorded and produced in Pittsburgh by Matt Very of Very Tight Recordings. Chock-full of swampy guitar licks, syncopated vocal delivery, and catchy beats, the EP fulfilled Jeffries' lifelong dream of creating soulful blues music. More significantly, the creation of this EP sparked a collaboration between Jeffries and drummer Garrett Grube, who created and recorded the drums for every song on the EP. A few jam sessions and a couple new songs later, the two-piece became a quartet when Grube invited bassist Josh Chamberlain to jam in Grube's college house basement, who then invited lead guitarist Evan Lawrence to join in the loud fun.

Today, Single Jo hope to expand their musical reach as widely as possible. Following the successful release of their debut LP Kailua, the band continues to take the alt-rock world by storm with their latest release Anonymity.
