Problem: Background: Herb Jeffries (born Umberto Alexander Valentino; September 24, 1913 - May 25, 2014) was an African-American actor of film and television and popular music and jazz singer-songwriter, known of his baritone voice. He was of African descent and Hollywood's first singing black cowboy. In the 1940s and 1950s Jeffries recorded for a number of labels, including RCA Victor, Exclusive, Coral, Decca, Bethlehem, Columbia, Mercury and Trend. His album Jamaica, recorded by RKO, is a concept album of self-composed calypso songs.
Context: From Detroit, at the urging of Louis Armstrong, Jeffries moved to Chicago where he performed in various clubs. One of his first gigs was in a club allegedly owned by Al Capone. Jeffries began his career working with Erskine Tate and his Vendome Orchestra. Tate signed the 19-year-old Jeffries to a contract with his Orchestra at the Savoy Ballroom in Chicago. His break came during the 1933 Chicago World's Fair A Century of Progress International Exposition singing with the Earl Hines Orchestra on Hines' national broadcasts live from the Grand Terrace Cafe. His first recordings were with Hines in 1934, including "Just to be in Carolina". By 1940, he was singing with the Duke Ellington Orchestra and then recorded with him from 1940 to 1942. His 1940 recording of "Flamingo" with Ellington, released in 1941, sold more than 14 million copies in its day. His name had been Herbert Jeffrey, but the credits on the record mistakenly called him Jeffries, so he renamed himself to match the typo. "Flamingo" was later covered by a white singer, the popular vocalist Tony Martin. During his time with the Duke Ellington Orchestra as a lead vocalist, Jeffries proved his talent as a mature singer, demonstrating his wide vocal range in such songs as "I Don't Know What Kind of Blues I've Got," "The Brownskin Gal," and "Jump for Joy" (all 1941). The 1944 single "My Little Brown Book" by Ellington and his Famous Orchestra, on which Jeffries provided vocals, reached No. 4 on Billboard R&B chart. Later on, Jeffries was replaced in the Ellington's band by Al Hibbler. In his teens, Jeffries had developed a fine voice, initially singing in higher registers. He started out his singing career as a lyrical tenor, but, on the advice of Duke Ellington's longtime music arranger, Billy Strayhorn, he lowered his range to mimic the vocal stylings of crooner Bing Crosby. Jeffries became a "silken, lusty baritone," according to music critic Jonny Whiteside. In 1945, Jeffries had a hit on the Billboard R&B chart with "Left A Good Deal In Mobile" (No. 2), on which he was accompanied by pianist Joe Liggins and his band Honeydrippers. Then, he moved to Europe and performed there for many years, including at nightclubs he owned. He was back in America by the 1950s, recording jazz records again, including 1957 collection of ballads, Say It Isn't So. In 1995, at age 81, he recorded The Bronze Buckaroo (Rides Again), a Nashville album of songs on the Warner Western label.
Question: When did his music career begin?
Answer: Tate signed the 19-year-old Jeffries to a contract with his Orchestra at the Savoy Ballroom in Chicago.

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."
