Blackline was formed in 2004. Formed in Boston, Massachusetts, they grew a hard rock feel. As a whole, they play with deftness, with a masterful command of the sound that radiates from their instruments. The influence of Metallica can be felt throughout the album. They released their debut album "blackline" in early 2006. Steven (vocals), Nathaniel (guitar), Matt (bass), and Jerry (drums) combine to make a heavy and emotional feel to their music.
