Background: Cudi was born Scott Ramon Seguro Mescudi on January 30, 1984, in Cleveland, Ohio, and grew up in Shaker Heights and Solon. He is the youngest of four children, with two brothers, Domingo and Dean, and a sister, Maisha. His mother, Elsie Harriet (Banks), is a middle-school choir teacher at Roxboro Middle School in Cleveland Heights, Ohio. His father, Lindberg Styles Mescudi, was a house painter, substitute teacher and World War II Air Force veteran.
Context: Kid Cudi's musical style has been described as "an atmospheric take on melodic rap, with a dollop of charming, off-key singing". He has also been called "introspective, with the ability to lay his insecurities on record and expose his fallibility." In 2015, Kris Ex of Billboard, wrote "he's always been an emotional artist, dealing with expansive and nebulous feelings in acute and often destructive ways." Kid Cudi's sound is what inspired and led Kanye West to create his cathartic 808s & Heartbreak (2008), with West later stating that he and Cudi were "the originators of the style, kinda like what Alexander McQueen is to fashion.... Everything else is just Zara and H&M." West also complimented Cudi by saying, "His writing is just so pure and natural and important." In March 2014, Cudi talked about wanting to provide guidance for young listeners with his music: "my mission statement since day one [...] all I wanted to do was help kids not feel alone, and stop committing suicide."  In a 2013 article for The BoomBox, the author wrote: "On [A Kid Named Cudi], Cudi raps and croons over samples and interpolations of Gnarls Barkley, Paul Simon, Band of Horses, J Dilla, Nosaj Thing, N.E.R.D. and Outkast. He melded indie rock, electronica and dubstep seamlessly with hip-hop without pandering or reaching. Before Drake broke through with 2009's So Far Gone, rapping and singing over Swedish indie poppers Lykke Li and Peter Bjorn and John, Cudi tweaked with multi-genre covers and seamless transitions between singing and rapping." In a 2009 interview with HipHopDX, when speaking on his debut album Cudi stated: "Well one thing I wanted to do was combine sounds that really bring out intense moods."  Kid Cudi's music has also been described as trip hop. Furthermore, he is known for harmonizing and humming in his music, which helps formulate his signature sound. On 2011's WZRD and 2015's Speedin' Bullet 2 Heaven, Cudi incorporated the use of screamed vocals, and can be heard yodeling on his 2016 album Passion, Pain & Demon Slayin'. Throughout the years he has also incorporated elements of psychedelia, R&B, electronica, synthpop and grunge, in his music.
