Alter Bridge are eight-time Rocktagon winners and are looking to make it nine with their single "Addicted to Pain." They face South African trio Seether in tonight's (September 16) match with their new single, um, "Seether."

Alter Bridge are releasing their upcoming album, Fortress, in three weeks. The October 8 release date will be followed by an extensive tour in Europe this fall.

Seether are planning to release their first greatest hits album, simply entitled Seether: 2002-2013. The two disc set will contain their most well-known hits and B-sides and rarities. The collection will also feature three all-new tracks, including their cover of '90s alt-rockers Veruca Salt's "Seether," the source of the band's name. It's surprising it took this long for the "Fake It" hitmakers to cover the song.

Listen to both "Addicted to Pain" and "Seether" below and vote for who you want to win.
