Problem: Background: Kelis Rogers was born and raised in the Harlem neighborhood of Manhattan in the Frederick Douglass Houses. Her first name is a portmanteau of her father's name, Kenneth (1944-2000), and her mother's name, Eveliss. Her father Kenneth was an African American jazz musician and Pentecostal minister, and was formerly a professor at Wesleyan University. Her mother Eveliss is a Chinese-Puerto Rican fashion designer who inspired Kelis to pursue her singing career.
Context: Kelis contributed a track titled "80's Joint" to the soundtrack of the 2006 dance film Step Up. She collaborated with Busta Rhymes and will.i.am on the track "I Love My Bitch", the second single from Rhymes's 2006 album The Big Bang. This was the second time Kelis teamed up with Rhymes, the first being his 2001 song "What It Is".  Kelis's fourth studio album, Kelis Was Here, was released in August 2006, and debuted and peaked at number ten on the Billboard 200. Despite the career-high debut, the album has sold only 157,000 copies in the United States as of 2007, according to Nielsen SoundScan. Its lead single, "Bossy" (featuring Too Short), achieved frequent airplay on urban radio and was a moderate hit in the U.S., peaking at number 16. "Bossy" went multi-platinum as a mobile phone ringtone, according to the RIAA. Kelis Was Here was nominated for Best Contemporary R&B Album at the 2007 Grammy Awards.  The second single released from the album by her American label, Jive, was a collaboration with Nas, "Blindfold Me". The song missed the Billboard Hot 100 and reached number 91 on the R&B chart. Her European label, Virgin, instead released the Cee-Lo-featuring "Lil Star", which was another hit for Kelis in the United Kingdom, peaking at number three. In the UK, Kelis Was Here charted at number 41 and has sold 60,000 copies, earning a silver certification from the BPI. In Australia, the album reached number 96 on the ARIA Albums Chart and the track "I Don't Think So" was used in promotion for the 2008 season of the reality series Big Brother Australia. The song subsequently peaked at number 27 on the ARIA chart and became a top ten urban hit. During mid 2007, Kelis toured in Europe, appearing in numerous festivals across the United Kingdom, France, and Germany, such as Wireless, Rise and Gurtenfestival. Ford chose Kelis to help advertise the 2007 Ford Edge, and she recorded a theme song for the commercial, entitled "Push It to the Edge", with help from producer Scott Storch.  According to Kelis, she received no support from Jive Records for Kelis Was Here, and the label dropped her in late 2007. Her manager at the time said that the singer was working with Cee-Lo Green on an alternative dance album and would be shopping a pop album produced by songwriter Guy Chambers, who co-wrote hits such as Robbie Williams's "Angels". Scottish electronica producer Calvin Harris was also said to be collaborating with her. Kelis later said of this period, "I was like, 'I will never put out another record again, I hate this business, I hate all these people.' I was in this race that I didn't even realise that I was in. I woke up and ten years had passed. That was never my plan". She subsequently took a hiatus from music.  After Kelis left Jive, the label released a fourteen-track greatest hits album entitled The Hits in March 2008. The album does not contain any previously unreleased songs; Ol' Dirty Bastard's "Got Your Money", N.E.R.D's "Truth or Dare", and Richard X's "Finest Dreams" appear on the album alongside every charted Kelis single to that date, with the exception of "Blindfold Me".
Question: what happened in 2007?
Answer: Kelis Was Here was nominated for Best Contemporary R&B Album at the 2007 Grammy Awards.

Background: Bernard Mathew Leadon III (pronounced led-un; born July 19, 1947) is an American musician and songwriter, best known as a founding member of the Eagles. Prior to the Eagles, he was a member of three pioneering and highly influential country rock bands: Hearts & Flowers, Dillard & Clark, and the Flying Burrito Brothers. He is a multi-instrumentalist (guitar, banjo, mandolin, steel guitar, dobro) coming from a bluegrass background. He introduced elements of this music to a mainstream audience during his tenure with the Eagles.
Context: Leadon was born in Minneapolis, one of ten siblings, to Dr. Bernard Leadon Jr. and Ann Teresa (nee Sweetser) Leadon, devout Roman Catholics. His father was an aerospace engineer and nuclear physicist whose career moved the family around the U.S. The family enjoyed music and, at an early age, Bernie developed an interest in folk and bluegrass music. He eventually mastered the 5-string banjo, mandolin and acoustic guitar.  As a young teen he moved with his family to San Diego, where he met fellow musicians Ed Douglas and Larry Murray of the local bluegrass outfit, the Scottsville Squirrel Barkers. The Barkers proved a breeding ground for future California country rock talent, including shy, 18-year-old mandolin player Chris Hillman, with whom Leadon maintained a lifelong friendship. Augmented by banjo player (and future Flying Burrito Brother) Kenny Wertz, the Squirrel Barkers eventually asked Leadon to join the group, upon Wertz's joining the Air Force in 1963.  His stint in the Scottsville Squirrel Barkers did not last long. In late 1963, his family once again relocated to Gainesville, Florida, when his father accepted a position as Professor of Aerospace Engineering at the University of Florida. Leadon attended Gainesville High School, where he met classmate and future Eagles lead guitarist Don Felder, whose band, the Continentals, had just lost guitarist Stephen Stills. Upon Leadon's joining the group, rechristened Maundy Quintet, they gigged locally, even sharing the bill with future Gainesville legend Tom Petty and his early band the Epics (a band that also included Bernie's brother, musician Tom Leadon).  A call from ex-Squirrel Barker Larry Murray in 1967, to join his fledgling psychedelic country-folk group, Hearts & Flowers, was enticing enough for Leadon to return to California, where he soon became involved with the burgeoning L.A. folk/country rock scene. Leadon recorded one album with the band, their second release Of Horses, Kids, and Forgotten Women for Capitol Records. The record was a local hit but failed to make much of a dent on the national album charts. Discouraged, the group disbanded the following year.
