Drive Like Jehu: Drive Like Jehu is an American post-hardcore band from San Diego active from 1990 to 1995.  Formed by rhythm guitarist and vocalist Rick Froberg and lead guitarist John Reis following the breakup of their band Pitchfork, the band's lineup also included bassist Mike Kennedy and drummer Mark Trombino.  Their music was characterized by multisectioned compositions, interlocking guitar patterns, orchestrated builds and releases, and elliptical melodies that produced a distinctive sound amongst other post-hardcore acts and impacted the evolution of hardcore punk into emo.

Eucalyptus (Pitchfork album): Eucalyptus is a studio album by the post-hardcore band Pitchfork.  It was released in 1990 through Nemesis Records and re-released in 2003 by Swami Records.  The album is the band's only full-length studio album.  It was produced by guitarist John Reis and its artwork was created by singer Rick Froberg, who at the time used the stage name Rick Fork.

See You in Magic: See You in Magic is the debut album by the San Diego, California rock band The Night Marchers, released in 2008 by Vagrant Records and Swami Records.  The Night Marchers are the latest musical project of singer/guitarist John Reis, previously of Pitchfork, Drive Like Jehu, Rocket from the Crypt, the Hot Snakes, and the Sultans.  Reis announced the group's formation in August 2007, after all of his previous acts had broken up by January of that year.  The band also includes Beehive and the Barracudas guitarist Gar Wood, CPC Gangbangs bassist Tommy Kitsos, and former Delta 72 drummer Jason Kourkounis.  Wood and Kourkounis had previously recorded and performed with Reis in the Hot Snakes.  The band members are credited on the album using pseudonyms that they had used in their previous acts: Reis is credited as "Speedo" (his stage name in Rocket from the Crypt), Wood as "Dner" (Beehive and the Barracudas), Kitsos as "Skitsos" (CPC Gangbangs), and Kourkounis as "Jsinclair" (Hot Snakes).

Pitchfork (band): Pitchfork was an American post-hardcore band formed in 1986 in San Diego, California and disbanded in 1990.  They are most well known as the first "real" band (after high school effort Conservative Itch/Coitus Interruptus) of guitarist John Reis, who would later gain fame as the frontman in Rocket from the Crypt, and as the first collaboration between Reis and singer Rick Froberg (the two would later form Drive Like Jehu and Hot Snakes).  As an aspiring visual artist and illustrator, Froberg provided most of the band's artwork while Reis developed his studio skills by acting as producer on their records.

John Reis: John Reis (born 1969) and also known by the pseudonyms Speedo, Slasher, and The Swami is an American musician, singer, guitarist, record label owner, and disc jockey.  He is best known as the singer and guitarist for the rock band Rocket from the Crypt, which he formed and fronted (as Speedo) for the entirety of its career from 1990 to 2005.  Prior to this he was the guitarist in the post-hardcore band Pitchfork, and also played in Drive Like Jehu during the early 1990s.  In 1999 he formed the Hot Snakes, and in 2000 also formed the Sultans, in which (as Slasher) he sang and originally played bass before switching to rhythm guitar.  He played in both these bands until their breakups in 2005 and 2007 respectively.  He also released a solo recording under the name Back Off Cupids, which was recorded in 1994 but not released until 1999.  Over the years he has performed in many other musical acts including Conservative Itch, Stacatto Reads, Custom Floor, and Beehive & the Barracudas.  He is the owner of Swami Records, a label he founded in 1999 (he uses the title The Swami in this capacity).  He frequently works with bands in a studio capacity and releases albums by many southern California groups through his label.  He also hosts the "Swami Sound System" program (previously on San Diego radio station 94.9 (KBZT), and now available on Slacker Radio).  Reis remains an influential figure in the San Diego underground music community and is currently performing with a new band named The Night Marchers.

Ghost Ship (album): Ghost Ship is the first album by the San Diego, California, rock and roll band Sultans, released in 2000 by Swami Records.  Both the band and the album began as "side projects" for John Reis during time off from his main band, Rocket from the Crypt.  This was also the time at which Reis formed Hot Snakes.  Reis collaborated with drummer Tony Di Prima, bringing in Rocket From the Crypt guitarist Andy Stamets while Reis himself played the bass guitar (he is normally known as a guitarist).  The band chose the name Sultans for the project and recorded an introductory EP and "Ghost Ship", both of which were released that year on Reis' newly formed Swami label.  As Reis has a tradition of using different stage names or pseudonyms in his various projects, he chose to be known as "Slasher" in the Sultans, while Stamets chose the nickname "Black Flame".

Automatic Midnight: Automatic Midnight is the first studio album by the San Diego, California post-hardcore band Hot Snakes, released in 2000 by Swami Records.  Both the band and the album began as a "side project" for John Reis in June 1999, during time off from his main band Rocket From the Crypt.  Reis wrote and recorded a batch of songs in San Diego with Delta 72 drummer Jason Kourkounis.  To provide vocals for the tracks Reis called in Rick Froberg, whom he had played with in Pitchfork and Drive Like Jehu from 1986 to 1995.  Most of the material from these sessions was used to create "Automatic Midnight", which became the first release for Reis' newly formed Swami Records label.
