The Smashing Pumpkins (or Smashing Pumpkins) are an American alternative rock band from Chicago, Illinois. Formed in 1988 by frontman Billy Corgan (lead vocals, guitar) and James Iha (guitar), the band included D'arcy Wretzky (bass guitar) and Jimmy Chamberlin (drums) in its original incarnation. It has undergone many line-up changes over the course of its existence, with the current lineup being Corgan, Chamberlin, Iha and guitarist Jeff Schroeder. Disavowing the punk rock roots of many of their alt-rock contemporaries, they have a diverse, densely layered, and guitar-heavy sound, containing elements of gothic rock, heavy metal, dream pop, psychedelic rock,progressive rock, shoegazing, and electronica in later recordings.
With the breakthrough of alternative rock into the American mainstream due to the popularity of grunge bands such as Nirvana and Pearl Jam, the Smashing Pumpkins were poised for major commercial success. At this time, the Smashing Pumpkins were routinely lumped in with the grunge movement, with Corgan protesting, "We've graduated now from 'the next Jane's Addiction' to 'the next Nirvana', now we're 'the next Pearl Jam'."  Amid this environment of intense internal pressure for the band to break through to widespread popularity, the band relocated to Marietta, Georgia in late 1992 to begin work on their second album, with Butch Vig returning as producer. The decision to record so far away from their hometown was motivated partly by the band's desire to avoid friends and distractions during the recording, but largely as a desperate attempt to cut Chamberlin off from his known drug connections. The recording environment for Siamese Dream was quickly marred by discord within the band. As was the case with Gish, Corgan and Vig decided that Corgan should play nearly all of the guitar and bass parts on the album, contributing to an air of resentment. The contemporary music press began to portray Corgan as a tyrant. Corgan's depression, meanwhile, had deepened to the point where he contemplated suicide, and he compensated by practically living in the studio. Meanwhile, Chamberlin quickly managed to find new connections and was often absent without any contact for days at a time. In all, it took over four months to complete the record, with the budget exceeding $250,000.  Despite all the problems in its recording, Siamese Dream debuted at number ten on the Billboard 200 chart, and sold over four million copies in the U.S. alone. Alongside the band's mounting mainstream recognition, the band's reputation as careerists among their former peers in the independent music community was worsened. Indie rock band Pavement's 1994 song "Range Life" directly mocks the band in its lyrics, although Stephen Malkmus, lead singer of Pavement, has stated, "I never dissed their music. I just dissed their status." Former Husker Du frontman Bob Mould called them "the grunge Monkees", and fellow Chicago musician/producer Steve Albini wrote a scathing letter in response to an article praising the band, derisively comparing them to REO Speedwagon ("by, of and for the mainstream") and concluding their ultimate insignificance. The opening track and lead single of Siamese Dream, "Cherub Rock", directly addresses Corgan's feud with the "indie-world".  In 1994 Virgin released the B-sides/rarities compilation Pisces Iscariot which charted higher than Siamese Dream by reaching number four on the Billboard 200. Also released was a VHS cassette titled Vieuphoria featuring a mix of live performances and behind-the-scenes footage. Following relentless touring to support the recordings, including headline slots on the 1994 Lollapalooza tour and at Reading Festival in 1995, the band took time off to write the follow-up album.

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.
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.
