Another night, another GRD Rocktagon as Papa Roach return for another round after disposing of Baroness with their new single, "Still Swingin'". This time Jacoby Shaddix and the boys take on blues-rock duo The Black Keys and their latest track, "Little Black Submarines".

"Little Black Submarines" is off of The Black Keys' seventh studio album, El Camino. The record propelled the band to arena rock status, selling out New York City's legendary Madison Square Garden in minutes. The Black Keys filmed the music video for "Little Black Submarines" at the Springwater Supper Club in Nashville, TN last month.

Papa Roach are releasing their lucky number seven album, The Connection, on October 2. They are part of the 2012 Rockstar Energy Drink Uproar Festival, which GRD will bring to town August 21 at Rock The Rapids.

Listen to "Still Swingin'" and "Little Black Submarines" below, then vote for who you want to be the Rocktagon champion.
