At midnight last night, intrepid music fans piled into Brooklyn’s Goodbye Blue Monday to see Gunfight! play it’s brand of southern-style rock. The band, whose members actually hail from New Jersey and Westchester County, have released an alt-country LP called “Frontier Land” packed with wailing vocals, driving bass lines and raucous, power chord-ready guitars. Songs like “Broke With Holes” sound like early Kings of Leon, except that Gunfight! singer Drew Mintz had tongue-in-cheek twang as he howled “You remind me of the road that I heard can save my soul, but who can afford the gas?” The band’s songs were dotted with banter between them and a set of fanatics, once even rearranging the band’s set list so a female fan could have a cigarette and not miss her favorite song. That song, “Sticks,” was the centerpiece of the band’s blues rock set, and had the crowd shouting it’s trailer park love song chorus: “I’m gonna be as drunk as a dog, live my life in the sticks with you!” This sort of working class aesthetic matched Goodbye Blue Monday’s flea market decorations, which included merry-go-round horses covered in christmas lights and light fixtures covered with homemade blue umbrella lamp covers. The band jerked around the stage laughing and play-fighting with one another once joking “It’s not called Gun-get-along!” For those night owls at the show, the band’s easy-going attitude and whiskey-soaked rock and roll kept them on their feet, and promised future success for the scrappy foursome.
