Problem: Background: Mary Christine Brockert (March 5, 1956 - December 26, 2010), better known by her stage name Teena Marie, was an American singer-songwriter, and producer. She was known by her childhood nickname Tina before taking the stage name Teena Marie and later acquired the nickname Lady Tee (sometimes spelled Lady T), given to her by her collaborator and friend, Rick James. She was known for her distinctive soulful vocals, which caused many listeners to believe she was African-American. Her success in R&B and soul music, and loyalty to these genres would earn her the title Ivory Queen of Soul.
Context: Contacted by Epic Records in the fall of 1982, after expressing dismay over her Motown contract, Teena Marie signed a worldwide deal with the Columbia Records subsidiary that also allowed her to establish her own publishing company, Midnight Magnet. Epic released the concept album Robbery, which featured the hit "Fix It" (#21 R&B), as well as "Shadow Boxing" and "Casanova Brown." (The latter was one of many tracks Teena Marie would write over the years about her real-life romance with one-time mentor Rick James. The relationship had ended by that point, but the two continued a sometimes tempestuous friendship until James' death, in August 2004.) In 1984, Teena Marie released her biggest-selling album, Starchild. It yielded her biggest hit "Lovergirl", which peaked at No. 4 on the U.S. Billboard Hot 100 chart in March 1985 and at No. 9 on the R&B chart. The label also released the moderate R&B hit "Out on a Limb", which peaked at No. 56 on the R&B chart but didn't break the Hot 100. "14k" was featured on the soundtrack of the film The Goonies (1985) but was not a hit (only making the U.S. R&B charts at #87). In 1986, Teena Marie released a rock music-influenced concept album titled Emerald City. It was controversial with her established fan base and not as successful as its predecessors. She also recorded the rock-influenced track, "Lead Me On", co-produced by Giorgio Moroder, for the soundtrack of the box office hit film Top Gun (1986). In 1988, she returned to R&B and funk, releasing the critically acclaimed album Naked to the World. That album contained the hit "Ooo La La La", which reached the top of Billboard's Hot R&B/Hip-Hop Singles & Tracks chart and was her only No. 1 single on that chart. During her 1988 Naked to the World concert tour, she suffered a fall and was hospitalized for six months. Teena Marie released Ivory in the fall of 1990; it scored no pop hits, but it did experience two R&B hits: "Here's Looking at You" (#11 R&B) and "If I Were a Bell" (#8 R&B).
Question: What musicians did she work with?
Answer:

Problem: Background: Adam Mitchel Lambert (born January 29, 1982) is an American singer, songwriter and stage actor. Since 2009, he has sold over 3 million albums and 5 million singles worldwide. Lambert rose to fame in 2009 after finishing as runner-up on the eighth season of American Idol. Later that year, he released his debut album, For Your Entertainment, which debuted at number three on the U.S. Billboard 200.
Context: Critics, celebrities and colleagues have been outspoken in their praise for Lambert's vocal command. Kathie Bretches-Urban, co-founder of Metropolitan Educational Theatre Network (now MET2) where Lambert performed as a youth, said "He has invested his entire life in music and performing ... He'd just come out onstage, and it popped". Record producer Rob Cavallo once described Lambert as having an unlimited range, and able to sing every note on a guitar from the lowest to the highest. In a March 2012 interview, rock artist Meat Loaf rated Lambert's voice in the company of only two others, Whitney Houston and Aretha Franklin, based on "that jet pack quality to their voice that just lets it take off." Lambert's total recorded vocal range spans from bass E to B flat above tenor high C (E2 - B5), giving him three octaves and six semitones. In 2011, when he took the stage at the MTV Europe Music Awards, honoree Queen guitarist Brian May noted that Lambert's voice has "sensitivity, depth, maturity, and awesome range and power which will make jaws drop"; while Roger Taylor added that Lambert had "the best range I've ever heard" in a BBC interview in 2012. Pharrell Williams, after collaborating with Lambert on his Trespassing album, commented, "This kid has a voice like a siren - there's no guys singing in that Steve Winwood-Peter Cetera range." In October 2012, British tabloid the Sunday Mirror reported that Lambert had insured his voice for $48 million. A source told the newspaper: "Insurance for stars is a big deal in the US and Adam's voice is his bacon."
