Context paragraphs:
Joe Lynn Turner: Joe Lynn Turner (born Joseph Arthur Mark Linquito, August 2, 1951) is an American singer, guitarist, songwriter, and producer.  He is known for his work in the hard rock bands Rainbow and Deep Purple.  During his career, Turner fronted and played guitar with pop rock band Fandango in the late 1970s; and in the early 80s, he became a member of Rainbow, fronting the band and writing songs with guitarist, Ritchie Blackmore and bassist, and producer, Roger Glover.  After Rainbow had disbanded (the first time) in March 1984, he pursued a solo career, released one album, Rescue You, and then later did session work, singing background vocals for the likes of Billy Joel, Cher, and Michael Bolton.  On the advice of Bolton, Turner began recording jingles for radio and television.  Other songs he had composed or through collaboration with songwriters like Desmond Child and Jack Ponti were being recorded and released by international recording artists Jimmy Barnes, Lee Aaron, and Bonfire.  Turner had a short-lived association with neoclassical metal guitarist Yngwie Malmsteen and then Deep Purple.  From the mid-1990s, he resumed his solo career, releasing an additional nine studio and two live recordings.  Turner did other session work, appearing as lead vocalist on tribute albums and working on projects involving various musical groups including progressive rock band Mother's Army; Bulgarian hard rock band Brazen Abbot; funk rock duo Hughes Turner Project; and classic rock/ progressive rock band Rated X.  In 2006, Frontiers Records approached Turner to become involved with the AOR side project Sunstorm.  By 2016, four albums under the Sunstorm name had been released.  That same year, Turner released "The Sessions" via Cleopatra Records featuring a veritable who's who of classic rock royalty as guest musicians, before resuming his seemingly constant touring schedule back in Europe

List of awards and nominations received by AC/DC: AC/DC are a hard rock band formed in Sydney, Australia in 1973 by brothers Angus and Malcolm Young.  Although the band are considered pioneers of heavy metal, its members have always classified their music as "rock 'n' roll".  AC/DC underwent several line-up changes before releasing their first album, "High Voltage", in 1975.  Membership remained stable until bassist Cliff Williams replaced Mark Evans in 1977.  In 1979, the band recorded their highly successful album "Highway to Hell".  Lead singer and co-songwriter Bon Scott died on 19 February 1980, after a night of heavy alcohol consumption.  The group briefly considered disbanding, but soon ex-Geordie singer Brian Johnson was selected as Scott's replacement.  Later that year, the band released their best-selling album, "Back in Black".  The band's next album, "For Those About to Rock We Salute You", was also highly successful and was their first album to reach number one in the United States.  AC/DC declined in popularity soon after the departure of drummer Phil Rudd in 1983.  Poor record sales continued until the release of "The Razors Edge" in 1990.  Phil Rudd returned in 1994 and contributed to the band's 1995 album "Ballbreaker". " Stiff Upper Lip" was released in 2000 and was well received by critics.  The band's new album "Black Ice" was announced in June 2008 and was released on October 20, 2008.  The album's first single, "Rock 'N Roll Train", earned AC/DC a Grammy nomination for Best Rock Group or Duo with Vocals.  Another "Black Ice" track, "War Machine," gained AC/DC their first Grammy Award win, for Best Hard Rock Performance.

Deep Purple, together with Led Zeppelin and Black Sabbath, have been referred to as the "unholy trinity of British hard rock and heavy metal in the early to mid-seventies".  They were listed in the 1975 "Guinness Book of World Records" as "the globe's loudest band" for a 1972 concert at London's Rainbow Theatre, and have sold over 100 million albums worldwide.

No. 4 (album): No. 4 (officially stylized as № 4) is the fourth album released by American hard rock band Stone Temple Pilots, released on October 26, 1999, by Atlantic Records.  The album was a return to the band's earlier hard rock roots, while also blending elements of heavy metal, psychedelic rock, and alternative rock.  Despite the lack of promotion due to singer Scott Weiland's one-year jail sentence shortly before the album's release, "No. 4" was certified Platinum by the RIAA on August 7, 2000, and by the CRIA in August 2001.  The song "Down" was nominated for Best Hard Rock Performance at the Grammy Awards.  The album also produced one of STP's biggest hits, "Sour Girl", which charted at #78 on the "Billboard" Hot 100, their only song to appear on that chart.  The CD was originally released as a digipak, then later changed to a standard jewel case.

Motorhead (Motörhead song): "Motorhead" is the eponymous song of the British hard rock band of the same name.  It was originally recorded by the space rock band Hawkwind, of whom the song's author, Motörhead frontman Ian "Lemmy" Kilmister, had been a member from 1971 to 1975.  It was the last song that he had written for them, but it had only been released as the B-side of the single "Kings of Speed", in March 1975.  In May of that year, Lemmy was fired from Hawkwind and formed a new band, naming it after the song.  It indicated the direction in which he planned to go: hard rock, not space rock.  Motörhead recorded two new versions of the song later that year, one as part of a demo session with producer Dave Edmunds and then another as part of the sessions for what was meant to have been Motörhead's debut album.  However, their record label, United Artists Records, decided to shelve the project and dropped the band without releasing any of the material.  Over a year later, the song was recorded yet again for Chiswick Records, during the session for their actual debut album and was released ahead of it, in June 1977, as their second 7" single.
