Vertical Man is the eleventh studio album by Ringo Starr, issued in 1998. The album served as Starr's attempt at a commercial comeback following the success of The Beatles Anthology project. Starr enlisted the help of many of his musician friends in making Vertical Man, including Scott Weiland, Brian Wilson, Alanis Morissette, Ozzy Osbourne, Tom Petty, Joe Walsh, Timothy B. Schmit, Steven Tyler, and his former Beatles bandmates Paul McCartney and George Harrison. Beatles engineer Geoff Emerick mixed the tracks, and Starr and Mark Hudson served as producers.
