Bi-Polar is the fourth studio album by Vanilla Ice. Released by Ultrax Records, it is the rapper's second independent release, after Hooked. The song "Unbreakable" was remade for Dance Dance Revolution II as "Still Unbreakable", with additional verses from Vanilla Ice himself and production from Konami in-house artist Des-ROW. As of 2002, the album sold 10,645 copies in the United States. Production The album was initially planned as a double album consisting of one disc of rock music (Skabz) and one disc of hip hop music (Bomb Tha System). Before its release, it was decided that the two parts of the album would be released on one disc, with each part labeled. Each side of the booklet features a different cover for each part. Skabz features appearances from heavy metal music figures such as former Slipknot guitarist Josh "Gnar" Brainard, Roy Mayorga, and Billy Milano. Bomb Tha System notably features appearances from Insane Poetry's Cyco, Chuck D (of Public Enemy fame), the Insane Clown Posse, and Wu-Tang Clan affiliate La the Darkman. In the initial publicity for the album, Vanilla Ice claimed that the album would feature a guest appearance from Lenny Kravitz.

The hardcore hip hop songs on the album, like "Detonator", "O.K.S." and "Unbreakable", focus on Ice's rhyming skills and flow.

In "Exhale", Ice claims that Marshall Mathers' initials
