Context paragraphs:
White Blues: White Blues is an EP by the Japanese noise musician Merzbow.  It is sometimes mistakenly call "Now" due to the cover.  It was released in a limited edition of 500 copies, the first 100 were hand numbered and came in a hand painted sleeve with the inner sleeve made up of hardcore porn pictures.

The Midnight: The Midnight is the name of the third EP released by electronica duo Lemon Jelly, according to the insert of "Lemonjelly.ky", on July 17, 2000.  It was limited to 1,000 10 in copies, the first 200 of which featured hand screen-printed sleeves.  The tracks from the EP were later incorporated for more accessible listening into the critically acclaimed "Lemonjelly.ky" album.  The cover had silver foil stamped on the inner sleeve and die-cut holes in the outer sleeve so when the record was pulled out of its sleeve, the stars twinkled in the night sky.

Optical Race: Optical Race is the thirty-sixth album by Tangerine Dream.  "Optical Race" is the inaugural album of the Melrose Years era, as it is the first appearance of the band on the Private Music label, founded by former Tangerine Dream member Peter Baumann.  It was their first album without Christopher Franke since 1970's "Electronic Meditation" and the band's first to be programmed largely with a computer, an Atari ST using Steinberg/Jones software.  The sleeve of the 12" release and the first release on CD and Compact Cassette features a die-cut outer sleeve with a multicolored inner sleeve.

The Yellow: The Yellow is the name of the second EP released by electronica duo Lemon Jelly, according to the insert of "Lemonjelly.ky", on September 6, 1999.  It was limited to 1,000 10" copies, the first 240 of which featured hand screen-printed sleeves.  The tracks from the EP were later incorporated for more accessible listening into the critically acclaimed "Lemonjelly.ky" album.  When the inner sleeve was pulled out, the Lemon Jelly logo appears briefly through a series of die-cut holes in the outer sleeve creating a piece of real world animation.

Pancho &amp; Lefty (album): Pancho & Lefty is a honky tonk album by outlaw country musicians Merle Haggard and Willie Nelson, released in 1983.  Original vinyl copies from 1983 give the album's title as "Poncho & Lefty" on the cover, as well as on the inner sleeve and the record label; the album's title track is similarly rendered "Poncho & Lefty" on the cover, inner sleeve, and label.  Later editions correct the title to the intended "Pancho & Lefty".

The Monty Python Instant Record Collection: The Monty Python Instant Record Collection is actually the title of two compilation albums released by the Monty Python troupe - the first in the UK in 1977 drew from the group's first five Charisma albums, and the other in the US in 1981 which comprised tracks from their four Arista albums.  It was billed as "the pick of the best of some recently repeated Python hits again, Vol.  II."  The record sleeve's original design was done by Terry Gilliam.  It featured packaging that folded out into a cardboard box resembling a large stack of record albums (all containing spoofs of popular album names).  An inner sleeve featured a spoof "Where Are They Now?"  update on the members of the Python team.

Sleeve valve (water): A sleeve valve is a device typically used in a water supply or distribution system when there is a need to reduce high pressure or throttle flow.  The sleeve valve consists of a cylindrical gate (tube) which slides over an inner sleeve.  The inner sleeve consists of a series of nozzles specifically sized and arranged to provide a solution to cavitation issues frequently encountered in throttling applications with other valve types.  Because of its design, it minimizes cavitation.  Cavitation that does occur in severe throttling conditions is directed from the valve down to center of the valve or pipe so that no erosion damage to the piping can take place.

Billie Joe Armstrong: Billie Joe Armstrong (born February 17, 1972) is an American musician, singer, songwriter and actor who is best known as the lead vocalist, primary songwriter, and guitarist of the punk rock band Green Day, which he co-founded with Mike Dirnt.  He is also a guitarist and vocalist for the punk rock band Pinhead Gunpowder and provides lead vocals for Green Day's side projects Foxboro Hot Tubs and The Network.

39/Smooth: 39/Smooth is the debut studio album by American punk rock band Green Day, released on April 13, 1990, by Lookout Records on vinyl (black and green) and cassette.  It is the band's only studio album to feature original drummer John Kiffmeyer.  Jesse Michaels of Operation Ivy contributed the artwork on the album.  The inner sleeve shows handwritten lyrics by Billie Joe Armstrong and letters by drummer John Kiffmeyer and Lookout owner Larry Livermore to I.R.S. Records, rejecting an offer to sign to the label and declaring its loyalty to Lookout!  Records (however, the band would later leave Lookout!  and move to a major label, Reprise Records).  Although it is currently out of print, "39/Smooth" was later rereleased, along with the group's two previous extended plays "Slappy", "1,000 Hours" and the song "I Want to Be Alone" (from "The Big One", a compilation album released by Flipside Records in 1990) on the compilation album "1,039/Smoothed Out Slappy Hours" in 1991.

Faust So Far: Faust So Far is a 1972 album by German krautrock group Faust.  This, the band's second studio album, has a more commercially typical structure than its predecessor; it comprises nine separate tracks, each consisting of an individual and distinct musical style or theme.  The album was issued in a black sleeve with black inner sleeve, black labels and a set of inserts with one print for each song on the album but these have reappeared in the currently available vinyl edition.
