Context paragraphs:
Deconstruction (band): Deconstruction was a band formed by former Jane's Addiction members, guitarist Dave Navarro and bassist Eric Avery.  Originally their former Jane's Addiction bandmate drummer Stephen Perkins was slated to be Deconstruction's drummer but instead joined Jane's Addiction frontman Perry Farrell's new band Porno for Pyros.  Drummer Michael Murphey was instead recruited for percussion duties.

Unshattered: Unshattered is the seventh solo studio album by English musician Peter Murphy.  It was released on 19 October 2004, through Viastar Records.  Produced by Gardner Cole, the album features contributions from various musicians, including Jane's Addiction members Stephen Perkins and Eric Avery, Porno for Pyros guitarist Peter DiStefano, former Bauhaus drummer Kevin Haskins and Canadian composer Ned Bouhalassa.

Pupil master: A pupil master ('pupilmaster' or 'pupil-master') or in the case of a female barrister, 'pupil mistress' etc., is the former name given to an experienced barrister who a pupil shadows during their pupillage.  The term pupil master or mistress has now been replaced by the term 'pupil supervisor'.  Barristers are called to the Bar via one of the four Inns of Court upon successful completion of the BPTC and having undertaken a required number of "qualifying sessions" in their chosen Inn of Court.  In most cases, the newly called barrister is then required to undertake training for a period of at least a year before the barrister can start their own private practice.  This training period is known as pupillage, usually split into two periods of six months known as "sixes".  The first "six" is a non-practising six, during which the pupil will shadow their pupil master; the second is usually a practising "six", when the pupil, with their pupil master's permission, can undertake the supply of legal services and exercise rights of audience in court.  Occasionally, a pupil barrister may undertake a third "six", extending the training period a further six months.  At the end of pupillage, to continue practising the law, a barrister may attempt to become a tenant in a set of barristers' chambers, or find a position as an employed barrister.

Pupil (band): Pupil is a Filipino rock band composed of Ely Buendia on lead vocals and guitars, Dok Sergio on bass, Wendell Garcia on drums and Jerome Velasco on lead guitar.

Hellride: Hellride is an American music group formed in the 1990s by guitarist Peter DiStefano, bassist Mike Watt, and drummer Stephen Perkins.  Hellride is a side project to the musicians' other full-time bands (Watt is active as a solo artist and former member of Minutemen and Firehose; DiStefano and Perkins were members of Porno For Pyros, with whom Watt occasionally played).

Pets (song): "Pets" is a song by alternative rock band Porno for Pyros and the second single from their 1993 self-titled album, "Porno for Pyros".  The Cursed Female / Cursed Male" single preceded "Pets," but saw only a limited radio station and promotional release, making "Pets" the first widely available commercial single from the album.

Porno for Pyros (album): Porno for Pyros is the eponymous debut album by Porno for Pyros, released on April 27, 1993 on the same label as Jane's Addiction, Warner Bros.  Records.  Jane's Addiction guitarist Dave Navarro and bassist Eric Avery, battling substance abuse issues, had left the band in 1991 in an attempt to stay clean, though the other half of the band wished to continue creating music.  The remaining members of Jane's Addiction, Perry Farrell and Stephen Perkins, were joined by guitarist Peter DiStefano and future Jane's Addiction bassist Martyn LeNoble, and continued under the new band name Porno for Pyros.  The band (and album) name is a reference to the 1992 Los Angeles riots, which are mentioned throughout the songs on the album as a recurring theme.

Banyan (album): Banyan is the debut album from Banyan, founded by Stephen Perkins of Jane's Addiction and Porno for Pyros fame, and David Turin.  This record is dedicated to Marc Perkins.  "They are compared to a deeply rooted Banyan tree which is ever increasing its hold on earth."

Porno for Pyros: Porno for Pyros were an American alternative rock band formed in Los Angeles, California in 1992, following the break-up of Jane's Addiction.  The band comprised former Jane's Addiction members Perry Farrell (vocals) and Stephen Perkins (drums), and Peter DiStefano (guitar) and Martyn LeNoble (bass).

Anytime at All: Anytime at All is the second album from Banyan, founded by Stephen Perkins of Jane's Addiction and Porno for Pyros fame, and David Turin.  This is a unique record in that it features nearly two dozens players, half of which are well-known.  Like their first album, this one is dedicated to Stephen's deceased brother, Marc Perkins.  This is a much more upbeat and organic sounding disc than the previous work, and the songs are much more varied.
