Question: Was it Dani Filth or Edwyn Collins that started a solo career?
Context: Losing Sleep is the seventh solo album by the Scottish singer-songwriter Edwyn Collins, released 13 September 2010 on Heavenly Records. Cradle of Filth was formed in Suffolk, England in 1991.  The band's original members consisted of vocalist Dani Filth, guitarist Paul Ryan, keyboardist Ben Ryan (Paul's brother), bassist John Pritchard and drummer Darren Gardner.  With this line-up, Cradle of Filth recorded a demo in 1992, titled "Invoking the Unclean".  Soon after, they recorded their second demo, "Orgiastic Pleasures Foul" with new guitarist Robin Eaglestone (aka Robin Graves) and new drummer Was Sarginson.  Robin left the band shortly afterwards, but following the departure of John Pritchard, Eaglestone returned to take his place as bassist.  Guitarist Paul Allender joined the band at the same time.  Following these changes, another demo was recorded, titled "Total Fucking Darkness" (released commercially in 2014, bolstered with rehearsal sessions and a surviving track from the abandoned "Goetia" album).  Sarginson left the band soon after, paving the way for the entry of drummer Nicholas Barker. "A Girl Like You" is a song by British singer-songwriter Edwyn Collins from his third solo studio album, "Gorgeous George" (1994).  The song samples the drums track of Len Barry's single "1-2-3" (1965). The Gospel of Filth: A Bible of Decadence & Darkness (formerly known as "The Gospel of Filth: A Black Metal Bible") is a book by Dani Filth and Gavin Baddeley, documenting the history of the band Cradle of Filth and straying further afield to explore their influences and "lay bare the fascinating underworld of contemporary culture". Dani Filth (born Daniel Lloyd Davey) is the lyricist, vocalist and founding member of the metal band Cradle of Filth. Devilment are a British heavy metal band originally formed in late 2011.  The band experienced problems finding a stable vocalist until Dani Filth from the extreme metal band Cradle of Filth joined.  They released their first studio album, "The Great And Secret Show", on 3 November 2014. Gorgeous George is the third solo studio album by Scottish musician Edwyn Collins.  The album was recorded at New River in London, with Collins acting as the producer. The Principle of Evil Made Flesh is the debut studio album by English extreme metal band Cradle of Filth.  It was released on 24 February 1994 through Cacophonous Records, following three demos released between 1991 and 1993.  The album's sound is significantly more raw than on subsequent releases, and frontman Dani Filth's vocals differ from his later style and technique.  The album is a then-unusual hybrid of gothic metal and black metal.  This would be the only album featuring guitarist Paul Ryan and keyboardist Benjamin Ryan; guitarist Paul Allender also left the band at this point, but returned five years later for "Midian". Edwyn Stephen Collins (born 23 August 1959) is a Scottish musician, producer and record label owner from Edinburgh, Scotland.  Collins was the lead singer for the 1980s post-punk band Orange Juice, which he co-founded.  Following the group's split in 1985, Collins started a solo career.  His 1994 single "A Girl Like You" was a worldwide hit. A Casual Introduction 1981/2001 is an album by Scottish musician Edwyn Collins.  It is a collection of both his solo work and also work of Orange Juice, the band he fronted from 1979 to the mid-80s.
