Planet P Project is a pseudonym used by American rock musician Tony Carey for his science-fiction themed, progressive rock/space rock music. Carey has released six albums under the Planet P Project name: Planet P (1983, later retitled Planet P Project), Pink World (1984), Go Out Dancing, Part I (1931) (2005), Go Out Dancing, Part II (Levittown) (2008), Go Out Dancing, Part III (Out in the Rain) (2009) and Steeltown (2013). Music videos for singles from the first albums received heavy to moderate airplay on MTV, when originally released. Pink World was originally a two-record set, released on bright-pink-colored vinyl.
Planet P's most well known singles were "Why Me?" (a sweeping, energetic romp about outer space and isolation), and the downbeat "Static". Go Out Dancing, Part I (1931) is the first of the trilogy, with part two titled Go Out Dancing, Part II (Levittown) and part three as Go Out Dancing, Part III (Out in the Rain).
The project's name was inspired from the fictional "Planet P" in Robert A. Heinlein's book Starship Troopers.

Procol's Ninth is the eighth studio album (ninth including Live) by Procol Harum, and was released in September 1975. Produced by songwriters Jerry Leiber and Mike Stoller, Procol's Ninth featured a slightly different direction from the previous album, with a much more stark sound than Chris Thomas's more elaborate productions. According to an interview with guitarist Mick Grabham, conducted by Roland Clare for the 2009 reissue, Leiber and Stoller focused less on the production sound and more on "the structure of the songs". The band appeared on the cover of the album in a straightforward unassuming photograph, mirroring the sound of the album itself. The cover featured simulations of each band member's signature.

Grand Hotel is the sixth studio album by Procol Harum. Released in 1973, it signalled a change of direction for the band. Guitarist Dave Ball who had joined the band for their live album the previous year left shortly after the photo shoot for the proposed album's cover to be replaced by Mick Grabham. Grabham's head was superimposed on the front and back cover of the album on Ball's body. Although the band had gone through significant personnel changes in previous years, the band would enter its most stable phase with this line up.

A Salty Dog has an ostensibly nautical theme, as indicated by its cover (a pastiche of the famous Player's Navy Cut cigarette pack). Interspersed with straight rock, blues and pop items, A Salty Dog showed a slight change of direction from its predecessors, being thematically less obscure. The title track itself was the first Procol track to use an orchestra, as would be referred to in the live album performance released some three years later.
The album was the first record produced by Matthew Fisher, who quit the band soon after its release. This was also the last Procol Harum album to feature bass guitarist Dave Knights.
