Sky Ferreira (born July 8, 1992), is an American singer, songwriter, model, and actress. On March 22, 2011, Ferreira released her first digital extended play, As If!.

Ferreira is of Portuguese, Brazilian and Native American descent. She got her start in Los Angeles. She sang gospel songs in church throughout her childhood. Sky grew up around family friend Michael Jackson, stating in an interview: "We just became friends with him. When I was born, I was raised around him, I always saw him. I had holidays with him and stuff like that." At age 13, she started taking opera lessons to refine her singing voice. She spent the next few years maintaining a MySpace profile where she uploaded various demos of self-written tracks. Shortly before her 15th birthday, she caught the attention of Swedish producers Bloodshy & Avant by sending them a message through the social networking site. The producers were impressed and subsequently decided to work with her.

Ferreira is musically influenced by former Spice Girls bandmate Emma Bunton,Michael Jackson, Prince, Blondie, Elton John, David Bowie, Serge Gainsbourg, Meja, Lil Kim, Nicki Minaj. She also cites stars like Madonna, Britney Spears, Gwen Stefani, Alice Cooper, Nancy Sinatra and The Runaways as her musical role models.

James Marshall "Jimi" Hendrix (born Johnny Allen Hendrix; November 27, 1942 – September 18, 1970) was an American musician and singer-songwriter. He is widely considered to be the greatest electric guitarist in music history, and one of the most influential musicians of his era despite mainstream exposure limited to just three years. After initial success in Europe with his group The Jimi Hendrix Experience, he achieved fame in the United States following his 1967 performance at the Monterey Pop Festival. Later, he headlined the iconic 1969 Woodstock Festival and the 1970 Isle of Wight Festival. He often favored raw overdriven amplifiers with high gain and treble and helped develop the previously undesirable technique of guitar amplifier feedback.

Hendrix helped to popularize use of the wah-wah pedal in mainstream rock, which he often used to deliver tonal exaggerations in his solos, particularly with high bends, complex guitar playing, and use of legato. As a record producer, he also broke new ground in using the recording studio as an extension of his musical ideas. He was one of the first to experiment with stereophonic phasing effects for rock recording.^{[citation needed]} He was influenced by blues artists such as B.B. King, Muddy Waters, Howlin' Wolf, Albert King and Elmore James,rhythm and blues and soul guitarists Curtis Mayfield and Steve Cropper, and the jazz guitarist Wes Montgomery. Hendrix began dressing and wearing a moustache like Little Richard when he performed and recorded in his band from March 1, 1964 through to the spring of 1965. In 1966, he stated, "I want to do with my guitar what Little Richard does with his voice".

Gucci Mane has released many other mixtapes and independent albums as well.

While serving a six-month jail term for assault in late 2005, Davis was charged with murder, though the charges were later dropped due to a lack of evidence. In 2009, he served a year-long county jail sentence for violating probation for his 2005 aggravated assault conviction.

Davis was born in Birmingham, Alabama, and later moved with his single mother to Atlanta. He enjoyed writing poetry as a child, and began rapping at age 14.

In 2005, Davis released his independent debut album entitled Trap House, which featured the successful single "Icy" with Young Jeezy. Disputes over the rights to this single caused a rift between the two artists. Hard to Kill followed in 2006. Hard To Kill included the hit single "Freaky Gurl". The song peaked at number 12 on the Hot Rap Tracks, number 19 on the Hot R&B/Hip-Hop Songs, and at number 62 on the Hot 100.
