Ariana Grande

Grande's music career began with the soundtrack Music from Victorious (2011).

Roy Orbison

Roy Kelton Orbison (April 23, 1936 – December 6, 1988), nicknamed the Big O, was an American singer-songwriter and musician, known for his distinctive, powerful voice, complex compositions, and dark emotional ballads. Between 1960 and 1964, 22 of his songs placed on the Billboard Top 40, including "Only the Lonely", "Crying", and "Oh, Pretty Woman".

The combination of Orbison's powerful, impassioned voice and complex musical arrangements led many critics to refer to his music as operatic, giving him the sobriquet "the Caruso of Rock". His voice ranged from baritone to tenor, and music scholars have suggested that he had a three- or four-octave range. While most male performers in rock and roll in the 1950s and 1960s projected a defiant masculinity, many of Orbison's songs instead conveyed a quiet, desperate vulnerability. He was known for performing while standing still and solitary and for wearing black clothes and dark sunglasses, which lent an air of mystery.

Kid Cudi

Scott Ramon Seguro Mescudi (born January 30, 1984), better known by his stage name Kid Cudi (/ˈkɪd ˈkʌdi/ KID KUD-ee, often stylized KiD CuDi), is an American recording artist and actor from Cleveland, Ohio. Cudi first gained major recognition following the release of his first official full-length project, a mixtape titled A Kid Named Cudi (2008). The mixtape caught the attention of American rapper-producer Kanye West, who subsequently signed Cudi to his GOOD Music label imprint in late 2008. Cudi has since gone on to launch his own record label imprints, the now-dissolved Dream On and current independent label, Wicked Awesome Records. Initially a rapper, Cudi has since added singer, songwriter, record producer, guitarist, music video director and film composer, to his repertoire.

As of 2015, Cudi has released five studio albums as a solo artist. In 2008, his debut single "Day 'n' Nite", led him to prominence, reaching the top five of the Billboard charts. Cudi's debut album Man on the Moon: The End of Day (2009) was later certified gold by the Recording Industry Association of America (RIAA). In 2010, he released Man on the Moon II: The Legend of Mr. Rager, which was preceded by "Erase Me" and "Mr. Rager". Later in 2010, Cudi formed a rock band, now known as WZRD, with his long-time collaborator Dot da Genius, releasing one eponymous debut album, in early 2012. The album debuted at number one on the Top Rock Albums chart. In April 2013, Cudi released Indicud, which became his highest-charting album on multiple charts. In February 2014, Cudi unexpectedly released his fourth album, Satellite Flight: The Journey to Mother Moon, exclusively to digital retailers with no promotion.
