Another Side of Mars is the upcoming debut solo album by former Mötley Crüe guitarist Mick Mars. The album has been in the works since, when Mötley Crüe were on their farewell tour. Around this time, both Mars and former Crüe vocalist John Corabi expressed interest in working together again. The following year, Mars released snippets of two new songs recorded for the album entilted "Gimme Blood" and "Shake the Cage." This would remain the last new information on Mars' solo album until Mötley Crüe's 2022 Stadium Tour shows, where a teaser was played featuring a cartoon of Mars with the caption "2023."
Following his dismissal from Mötley Crüe, Mars confirmed additional details about his upcoming solo album in an interview with Rolling Stone in June 2023. He confirmed the album's title, alongside song titles "Killing Breed," "Broken on the Inside," "Alone," "Lonely in Your Grave," "Loyal to the Lie," "Decay," "Fear," "Memories" and "Erased."
