In an interview with Billboard, Anderson explained that "I started putting the album together properly about two years ago. But the oldest song on the album, “Never Better,” is about four years old. I’ve written hundreds of songs, and I was still writing new stuff when I was putting the album together. It was just a matter of deciding how to construct it as something that made sense of how I was feeling." He also noted Kanye West’s album The College Dropout as a source of personal inspiration for his music.[2]
You're a Man Now, Boy received very positive reviews from critics upon release. Writing for The Evening Standard, John Aizlewood gave the album 4 stars out of 5 and described Raleigh Ritchie as "bold and cutting edge in a Jack Garratt sort of way and the fabulous The Last Romance is a life-affirming combination of confessional vocals and a massed gospel singalong. And for all the electro clutter of 'Werld Is Mine', the throaty rasp to his vocals and the smoother soul of the Stormzy-featuring 'Keep It Simple', he never loses his pop heart."[4]
The Guardian's Dave Simpson likewise gave the album 4 stars out of 5. Noting the lengthy writing and production process for the album, "If the problematic gestation means the mix of soul, R&B, electronica and cinematic orchestral sweeps can occasionally feel a trifle uneven, the Bristolian’s emotional deliveries bring a compelling vulnerability and humanity to the narrative-verse-to-big-chorus format." Simpson notes the title track as a highlight, writing that the track's "comparison of childhood dreams with adult realities ('I was an astronaut, once upon a time. I'm not growing up. I'm ageing') is beautifully moving."
MTV's Matt Tarr wrote very positively about the album. Like Simpson, he notes the title track as a highlight of the album as well as 'Stronger Than Ever' and as "the most powerfully emotive tracks on the album, both featuring dramatic rises and falls before eventually building to intense climactic ending". He also wrote that The orchestral instrumental of the prior is truly noteworthy and wouldn’t find itself amiss in a thrilling cinematic film trailer." Concluding the review, Tarr wrote that the album "is an incredible way to mark the humble beginning of an emotionally honest and sensitive artist on the mainstream stage and Raleigh Ritchie’s raw-yet-tender style is a joy to behold. Sure to catch the ear of new fans and current loyalists alike, this album will set the foundations for an exciting and boundary-pushing career in the UK music spotlight for a long while to come."[6]
DJBooth's Lucas G. described the album as "a profoundly emotional album but just like in real life, that emotion is hidden under puns, smiles and spliff smoke. The thing I love most about the album is the way Ritchie wrestles with fear but doesn't wallow in. He stands at the top of the cliff staring into the void, occasionally dangling his feet over, but never jumping. At the same time the album struggles with adulthood identity, connections and love, the album has an upbeat, fresh sound to it."[3]
