Perfect Strangers is the eleventh studio album by Deep Purple, released in October 1984. It represents the first album recorded by the reformed, and most successful and popular, 'Mark II' line-up.[1] It was the first Deep Purple album in nine years, and the first with the Mk II lineup for eleven years, the last being Who Do We Think We Are in 1973. Ritchie Blackmore and Roger Glover arrived from Rainbow, Ian Gillan from Black Sabbath, Jon Lord from Whitesnake, and Ian Paice from Gary Moore band.

"Straight Between the Eyes" is the sixth LP released by "Rainbow", released in 1982. A remastered CD reissue, with packaging duplicating the original vinyl release, was released in May 1999. The band line-up was the same as had recorded the previous year's "Difficult to Cure" album, with the exception of David Rosenthal, who replaced Don Airey on keyboards. The title allegedly came from a phrase from Jeff Beck, describing Jimi Hendrix to Blackmore.

"Difficult to Cure" is the fifth album released by "Rainbow", in 1981, and marked a further commercialisation of the band's sound. In an interview in "Sounds" (July 25th 1981), a UK music paper, Blackmore openly stated his liking for "Foreigner" and erstwhile vocalist Ronnie James Dio has referred to this period of Rainbow as "Foreigner Junior". It is, however, a popular album with many fans, despite it being markedly different from the albums which preceded it.
