Background: D'Angelo was born Michael Eugene Archer, in Richmond, Virginia on February 11, 1974, to a Pentecostal preacher father. He was raised in an entirely Pentecostal family. Archer's musical talents were discovered very early on. At 3, he was spotted by his 10-year-old brother Luther, playing the house piano.
Context: D'Angelo signed a publishing deal with EMI Music in 1991 after catching the attention of record executives through a demo tape, which was originally by the group. After an impressive audition for EMI execs, a three-hour impromptu piano recital, D'Angelo was signed to a recording contract in 1993. A&R-man Gary Harris was primarily responsible for his signing, while manager Kedar Massenburg helped negotiate the contract as well. Massenburg became D'Angelo's manager after hearing of him through "the buzz on the streets". He had previously managed hip hop group Stetsasonic and formed the artist management-firm Kedar Entertainment in 1991, which he diversified into production, music publishing and publicity. In 1994, his first significant success came in the form of the hit single "U Will Know". D'Angelo co-wrote and co-produced the song for the all-male R&B supergroup Black Men United, which featured R&B singers such as Brian McKnight, Usher, R. Kelly, Boyz II Men, Raphael Saadiq and Gerald Levert. D'Angelo composed the music for "U Will Know", while his brother, Luther Archer, wrote the lyrics. Originally featured on the soundtrack to the film Jason's Lyric (1994), the single peaked at number 5 on the Hot R&B/Hip-Hop Singles & Tracks and at number 28 on the Billboard Hot 100. The music video for "U Will Know" featured D'Angelo as the group's choir director; he reprised the role for the live performance of the song at the Soul Train Music Awards. That same year, he wrote and produced the song "Overjoyed" for the Boys Choir of Harlem, which appeared on their studio album The Sound of Hope (1994). The success of "U Will Know" helped build the buzz surrounding D'Angelo, which was followed by a number of highly promoted showcases, and added to the buzz among music industry insiders. Brown Sugar was released in June 1995. Although sales were sluggish at first, the album was eventually a hit. The album debuted at number six on the US Billboard Top R&B Albums chart in the week of July 22, 1995. It ultimately peaked at number four in the week of February 24, 1996, and spent a total of 54 weeks on the chart. Brown Sugar also spent 65 weeks on the Billboard 200 and peaked at number 22 on the chart. It sold 300,000 copies within its two months of release. The album had been selling 35,000 to 40,000 copies a week through to November 1995, and by January 1996, it had sold 400,000 copies. With the help of its four singles, including the gold-selling Billboard Hot 100 hit "Lady" and R&B top-ten singles "Brown Sugar" and "Cruisin", the album reached sales of 500,000 copies in the United States by October 1995. On February 7, 1996, it was certified platinum by the Recording Industry Association of America, following shipments in excess of one million copies in the U.S. The album was certified gold in Canada on May 9, 2000. Its total sales have been estimated within the range of 1.5 million to over two million copies.
Question: When did he sing in Zurich and Brussels?
Answer:

Background: The Wallflowers are an American rock band formed in Los Angeles in 1989 by singer-songwriter Jakob Dylan and guitarist Tobi Miller. The band has gone through a number of personnel changes but has remained centered on Dylan. After releasing their eponymous debut album in 1992, the Wallflowers released what would become their best-known and highest-selling album, Bringing Down the Horse in 1996, which featured songs such as "One Headlight" and "6th Avenue Heartache". They went on to release an additional three albums before going on a seven-year hiatus, beginning in 2006.
Context: In 2001, Jakob Dylan began writing for the Wallflowers' fourth album, Red Letter Days. Later that year while on tour with John Mellencamp, the band began recording using portable equipment. Some recording was also done at keyboardist Rami Jaffee's house. Once the band was finished touring for the year they began recording the bulk of the new record at Jackson Browne's studio in Santa Monica. By the time the Wallflowers had gotten into Browne's studio, Michael Ward had left the band, leaving them without a lead guitarist for the recording process. Dylan took on much of the lead guitar duties with Mike McCready, Rusty Anderson and Val McCallum also contributing on guitar. Moe Z M.D., who had been touring with Mellencamp, contributed additional percussion and background vocals to the album.Red Letter Days was produced by founding Wallflowers member Tobi Miller along with Bill Appleberry. Recording continued through the new year and was completed on April 12, 2002. The album was mixed by Tom Lord-Alge, who had mixed the band's previous two albums. Mixing was completed on May 15, 2002. While the Wallflowers were working on Red Letter Days, they recorded a cover of the Beatles' 1965 song "I'm Looking Through You" for the soundtrack to the 2001 film I Am Sam. The soundtrack was released on January 8, 2002. The first single from the Red Letter Days, "When You're On Top," was released to radio on August 16, 2002. A music video directed by Marc Webb followed. After a few false starts, Red Letter Days was released on November 5, 2002. The album was met with mixed to positive reviews. Many critics noted the harder rock sound and catchy melodies used throughout the album. Commercial performance was relatively mixed as well, peaking at No.32 on the Billboard 200. Around the time of Red Letter Days' release the Wallflowers embarked on a monthlong U.S. tour stretching into early December. After another U.S. tour in January 2003, the Wallflowers toured in several European countries in February including Spain, Italy, Germany and Great Britain. After this tour, the Wallflowers' drummer since 1995, Mario Calire announced he was parting ways with the band. In 2003, the Wallflowers were featured on the soundtrack for the film American Wedding. The band recorded a cover of Van Morrison's 1970 song "Into the Mystic". The film's music department weren't able to secure the licensing rights to use Morrison's version so they enlisted the Wallflowers to cover the song. Both versions of the song were, however, featured in the film.
Question: Did they collaborate with any other artists?
Answer:
The album was mixed by Tom Lord-Alge, who had mixed the band's previous two albums.
