Not Natural at All is the sixth studio album by American singer Drew Hacks. It was released on December 28, 2038, Hacks' 42nd birthday, through his record label and production company Diamond Joint in association with Universal Music Group. The singer began writing songs for the album in early 2037; recording sessions started in October at the Diamond Joint studio in Los Angeles and lasted until September 2038. Initially scheduled for May 2039, the album was pushed back to December 2038 after Hacks decided to release it on his birthday and match the intimacy of its lyrical content. The album's engineering, editing, and final touches were rushed by Universal in order to fit Hacks' revised schedule. The record did not receive physical editions, being exclusive to streaming and music download platforms.
More intimate and minimalist than Hacks' previous releases, Not Natural at All is a psychedelic and dream pop record marked by breathy vocals, predominance of string instruments, personal lyrics, and angelical backing vocals. Lyrically, the album discusses a variety of themes centered on Hacks' personal and professional lives, including family issues, past shames, adulthood, drug dependence, anxiety, and pressure from the music industry, among others. The album is the longest in Hacks' discography and its songs adopt unconventional song structure. The final track listing features nine songs in which Hacks worked with nine previous collaborators and three songs in which the singer worked by himself. Hacks wrote or co-wrote the majority of the lyrics. The album's closure is a cover version of Kali Uchis' Isolation (2018) songs "Tomorrow" and "Coming Home".
Not Natural at All did not receive an intense marketing campaign nor a concert tour, as Hacks did for his previous studio albums. As a result, it debuted at number four on the US Billboard 200, becoming Hacks' first album not to debut atop the chart since his debut Strange Intentions of a Stilted One (2016). Not Natural at All eventually climbed to number one in the country. Two singles, "Hit 32" and "Milk", were issued the same day of the album's release; although critically acclaimed, the singles received lukewarm commercial performance. Upon its release, Not Natural at All was met with critical glorification by music journalism for its songwriting techniques, lyrical content, minimalist production, overall concept, and message. Hacks was singled out for his artistry and craftsmanship.
