Unpurified is the seventh full-length album from Garden Grove, CA Industrial Metal band Psoriasiss, the first featuring vocalist Laurence Jakobson. According to guitarist Orville Redd, "The sessions for Unpurified started almost immediately after Jakobson joined the band. We'd say this album is the next logical step in our evolution after both Mourningstar and The Fifth Chapter, which may or may not be hard to believe at first. Listen to this album and you'll see what I mean."
