Nightlife is the fourth studio album by Irish rock band Thin Lizzy, released on 8 November 1974 by Vertigo Records.

It was produced by Ron Nevison and bandleader Phil Lynott, and was the first album to feature the band as a quartet with newcomers Scott Gorham and Brian Robertson on guitars.

He singles out "She Knows" as "gently propulsive, [and] utterly addictive", but adds that there are "still moments of tough, primal rock 'n' roll", such as "It's Only Money" and "Sha-La-La".

[8] Martin Popoff judged the album "more enigmatic, sincere and philosophically complex than much else rock 'n' roll out there at the time", but also "too distant from the band's heart and soul" and overtly into black music, with Lynott "searching for ways to pay homage to his racial heritage.
