The In-Flight Feature is John McBain's debut solo effort released in 2006 on Brant Bjork's label Duna Records.
 The In-Flight Feature was the result of material accumulated over several years that McBain didn't think was suitable for his then current band the Wellwater Conspiracy.
 It is mainly instrumental with several songs having no vocals at all and is heavily influenced by 1970s space/progressive rock.
 Guest appearances include Jon Kleiman and Tim Cronin of Monster Magnet.

 This 1996 release was named by "NME" as one of the 500 greatest albums of all time.
 After the success of their full debut the band recruited Charlotte Hatherley as a guitarist and vocalist, releasing their second record "Nu-Clear Sounds" in 1998.
 After narrowly avoiding bankruptcy the band released "Free All Angels" in 2001 and a string of successful singles.

Argus is the third album by the rock band Wishbone Ash.
 It is the most popular Wishbone Ash album and widely considered their greatest by fans and reviewers.
 It was named "Album of the Year" in the 1972 year-end issue of "Sounds magazine".
 The album is medieval-themed, featuring a blend of progressive rock, folk, and hard rock, and is considered a landmark album in the progression of twin-lead guitar harmonisation later adopted by bands such as Thin Lizzy and Iron Maiden.
 The sound engineer on "Argus" was Martin Birch, who also worked with Deep Purple, later with Black Sabbath, Iron Maiden and other hard rock bands.
 The bulk of the melodies and lyrics were provided by bassist/lead vocalist Martin Turner, although all members contributed to the song arrangements.
