Problem: Background: Morello was born on May 30, 1964, in Harlem, New York, to Ngethe Njoroge and Mary Morello. Morello, an only child, is the son of an American mother of Italian and Irish descent and a Kikuyu Kenyan father. His mother was a schoolteacher from Marseilles, Illinois, who earned a Master of Arts at Loyola University, Chicago and traveled to Germany, Spain, Japan, and Kenya as an English language teacher between 1977 and 1983. His father participated in the Mau Mau Uprising and was Kenya's first ambassador to the United Nations.
Context: Morello is famed for his guitar style, which consists of heavy metal/punk hybrid riffs and hip hop-inspired sounds. A 1993 Melody Maker live review of a Rage Against The Machine gig, said "Guitarist Tom Morello wears his guitar high up to wring every sound out of it. Falling bombs, police sirens, scratching - he can do them all." To produce his guitar sounds, Morello chooses various effects pedals. During his tenure in RATM, he used a Dunlop Cry Baby, a DigiTech WH-1 Whammy, a Boss DD-2 Digital Delay, a DOD EQ pedal (set flat and just used to boost the volume during guitar solos or particular rocking moments), and an Ibanez DFL Flanger. Around the time of The Battle of Los Angeles he added a Boss TR-2 Tremolo pedal (which can be heard on "Guerrilla Radio"). For Audioslave, Morello replaced the Ibanez Flanger with an MXR Phase 90. His amplifier of choice has always been a 50-watt Marshall JCM 800 2205 and a Peavey 4x12 cabinet. While the Marshall amplifier has two channels, he only uses the overdrive channel, and simply lowers the volume on his guitar to get cleaner sounds. In the studio, Morello uses the same setup for the bulk of the guitar tracks. For The Battle of Los Angeles, he also used a few other amplifiers, such as a Line 6 as heard on the clean, spacey intro of "Mic Check", plus a Pignose mini-amplifier and a MusicMan "Twin" style amplifier. During the recording of Audioslave's last album, Revelations, Morello experimented with different amplifier setups. For the title track's solo he split his signal to his standard Marshall 2205 head and Peavey cabinet and a 100 watt Fender Bassman head and an Orange cabinet. With delay sent to one while the other is unaffected the sound is being "ping-ponged" between the two amplifiers. He also borrowed a Vox AC30 amplifier from producer Brendan O'Brien for some tracks. Morello's unique technique and talent led to him being voted the fifth greatest guitarist of the past 30 years in a 2010 BBC poll.

Answer:

Background: Beyonce Giselle Knowles was born in Houston, Texas, to Celestine "Tina" Knowles (nee Beyince), a hairdresser and salon owner, and Mathew Knowles, a Xerox sales manager. Beyonce's name is a tribute to her mother's maiden name. Beyonce's younger sister Solange is also a singer and a former back up dancer for Destiny's Child.
Context: Beyonce names Michael Jackson as her major musical influence. Aged five, Beyonce attended her first ever concert where Jackson performed and she claims to have realized her purpose. When she presented him with a tribute award at the World Music Awards in 2006, Beyonce said, "if it wasn't for Michael Jackson, I would never ever have performed." She admires Diana Ross as an "all-around entertainer" and Whitney Houston, who she said "inspired me to get up there and do what she did." She credits Mariah Carey's singing and her song "Vision of Love" as influencing her to begin practicing vocal runs as a child. Her other musical influences include Aaliyah, Prince, Lauryn Hill, Sade Adu, Donna Summer, Mary J. Blige, Janet Jackson, Anita Baker and Rachelle Ferrell. The feminism and female empowerment themes on Beyonce's second solo album B'Day were inspired by her role in Dreamgirls and by singer Josephine Baker. Beyonce paid homage to Baker by performing "Deja Vu" at the 2006 Fashion Rocks concert wearing Baker's trademark mini-hula skirt embellished with fake bananas. Beyonce's third solo album I Am... Sasha Fierce was inspired by Jay-Z and especially by Etta James, whose "boldness" inspired Beyonce to explore other musical genres and styles. Her fourth solo album, 4, was inspired by Fela Kuti, 1990s R&B, Earth, Wind & Fire, DeBarge, Lionel Richie, Teena Marie, The Jackson 5, New Edition, Adele, Florence and the Machine, and Prince. Beyonce has stated that she is personally inspired by Michelle Obama (the 44th First Lady of the United States), saying "She proves you can do it all" and she has described Oprah Winfrey as "the definition of inspiration and a strong woman". She has also discussed how Jay-Z is a continuing inspiration to her, both with what she describes as his lyrical genius and in the obstacles he has overcome in his life. Beyonce has expressed admiration for the artist Jean-Michel Basquiat, posting in a letter "what I find in the work of Jean-Michel Basquiat, I search for in every day in music... he is lyrical and raw". In February 2013, Beyonce said that Madonna inspired her to take control of her own career. She commented: "I think about Madonna and how she took all of the great things she achieved and started the label and developed other artists. But there are not enough of those women.".
