Hotel Diablo is the fourth studio album by American rapper Machine Gun Kelly.

Lyrically, the songs deal with problems with drugs, childhood family struggles, among other themes.

Shortly after releasing the bonus tracks to Bloom (2017), Kelly announced he was going to start recording "album 4".

[10][11][12] On April 2, 2019, MGK posted a 16-second video snippet of a song along with the album title on social media.

Its lyrical themes reveal mental struggles and drug problems, and being "all alone in a glass house".

[35] Markos Papadatos of the Canadian internet news service Digital Journal praised the lyrics and overall album sound and mood.

He wrote "Overall, Machine Gun Kelly has released a solid new album, Hotel Diablo.

Papadatos concluded with "Most impressive about Machine Gun Kelly is that the same energy that he exudes on this album, he displays on stage in a live setting, which is incredible."

Gone are the odd hooks and off-beat rapping from last year's project; they are replaced with intricate flows and a cohesive sound that spans across the entire production.

"[39] A negative review came from Dhruva Balram of NME, who said that "Despite the potency of its material, the project's lyricism feels apathetic.

While his contemporaries, from Juice WRLD to Post Malone, are pushing the envelope, crafting new sounds and forging new paths, MGK sticks to a tried-and-tested formula which, ultimately, feels bland.

He concluded that it was "a formulaic album that's been re-worked with the same puzzle pieces: clever wordplay, catchy beats and enough meat on its body to keep it alive.
