IN: Celtic Frost () were a Swiss heavy metal band from Zurich. They are known for their strong influence on the development of extreme metal. Formed in 1982 as Hellhammer, the band became Celtic Frost in 1984 and was active until 1993. It re-formed in 2001 and disbanded following frontman Tom Gabriel Fischer's departure in 2008.

One of their more influential recordings was 1985's To Mega Therion which did not feature Ain on bass, but stand-in Dominic Steiner. The cover artwork is a painting by H.R. Giger entitled Satan I. The album was a major influence on the then-developing death metal and black metal genres. Ain did return after the album was recorded however. In 1987 followed Into the Pandemonium. The album is more varied than many of Celtic Frost's past LPs, with unlikely covers (Wall of Voodoo's "Mexican Radio"), emotionally charged love songs, the album's recurring industrial-influenced rhythmic songs of demons and destruction, traditional Frost styled songs about dreams and fear, and a dark, classical piece with female vocals.  The album is vastly different from the band's previous work and cemented its late 80s avant-garde metal term; it is also a departure from the extreme style found on the band's previous albums, Morbid Tales and To Mega Therion that Celtic Frost had become known for. However, it does have the recurring symphonic elements found on previous albums. The album has a more classic heavy metal style within the songs with elements of industrial, classical and gothic rock, and even has an industrial/electronic body music (EBM)-inspired rhythm in "One in Their Pride". It does have a few black metal elements remaining in Warrior's vocals, though, and some thrash-influenced guitar riffs.  These albums were some of the pivotal LPs for underground metal and introduced a new and more varied sound. Celtic Frost, along with Venom and Bathory were pioneers in the still underground black metal scene, although Celtic Frost were much more experimental with the addition of classical instruments, operatic female vocals and sampling. Celtic Frost was often labeled by critics as avant-garde metal.

IN: Xenomania is an English songwriting and production team founded by Brian Higgins and based in Kent, England. Formed after Higgins met Miranda Cooper, Xenomania has written and produced for renowned artists such as Cher, Kylie Minogue, Dannii Minogue, Sophie Ellis-Bextor, Pet Shop Boys, The Saturdays and the Sugababes. In particular, all but one of Girls Aloud's studio albums have been entirely written and produced by Xenomania. Sugababes' "Round Round" and Girls Aloud's "Sound of the Underground" have been credited with reshaping British pop music for the 2000s.

Xenomania worked with American pop singer Britney Spears in 2003 during sessions for her fourth album In the Zone. The song submitted, "Graffiti My Soul", was not chosen for the album. While the record company loved the song, Spears felt that it needed more of a chorus. Higgins said that they wanted "essentially 'Sound of the Underground 2'." It later appeared on Girls Aloud's What Will the Neighbours Say?.  The production team were due to work with rock bands New Order and Franz Ferdinand, but both sessions proved fruitless. Xenomania was due to produce for New Order's Waiting for the Sirens' Call, but Peter Hook said they "scrapped the Brian Higgins stuff because we didn't like it. I thought he did quite a good job on Girls Aloud but he didn't do a good job on us." Franz Ferdinand's drummer Paul Thomson said, "We wrote with Higgins for a while and initially we thought we'd work more with him but it didn't really work out. We just realized that we're not really a pop group."  Xenomania were reported to have written five songs for Leona Lewis's second album, Echo (2009), described by Cooper as "tragic songs with a twist". The songs did not make the album. In 2012, Xenomania were reported to be working with Christina Aguilera.  Higgins spoke of bad experiences with bigger artists to Literally magazine in 2009:  "Everything about us is about enormous enthusiasm for something. And therefore big artists can come in and they think "they're the flavour of the whatever, let's take their thing and then we'll do what we want with it..." Well, no, that's not acceptable anyway. I've had that experience happen where the big artists were fine until they got into the mix room and then they basically pulled the record to pieces. So I took my name off the record and the writing credits off the record. Because they're assholes. And they sold about 20,000 copies, and they've never been seen since. So big artists are often jerks of the biggest order. And often people say don't meet your heroes because you'll be let down, and I sort of understand why people would say that."
