Question: Who created the band for which Patrice Guers was the former bassist?
Context: Rhapsody of Fire (formerly known as Rhapsody) is an Italian symphonic power metal band created by Luca Turilli and Alex Staropoli, widely seen as a pioneer of the symphonic power metal subgenre. Patrick Bruders is an American musician, best known as the current bassist for heavy metal supergroup Down, the former bassist of the blackened death metal band Goatwhore from 1997 to 2004, and the former bassist for the seminal sludge metal band Crowbar from 2005 until 2013.  In 2008 he joined Eyehategod side project Outlaw Order and began live bass duties for the band, but has since parted ways with the group.  He began touring as live bassist with heavy metal supergroup Down in early 2011, replacing former bassist Rex Brown, before being added as a permanent member, performing bass duties live and in the studio.  Bruders is also a member of the New Orleans-based crust punk band Gasmiasma, Austin-based country band Pure Luck, and joined legendary doom metal band Saint Vitus for their performance at the Hammer of Doom music festival in Würzburg, Germany. Jeanne Sagan is a musician from Springfield, Massachusetts.  She is the bassist and backing vocalist for the heavy metal band Crossing Rubicon, but is best known as the former bassist and backing vocalist for the heavy metal-metalcore band All That Remains from 2006 to 2015.  Before joining All That Remains, she was bassist in the band The Acacia Strain in 2003.  In 2006, she was asked to join All That Remains after bassist Matt Deis left the band.  She originally worked merchandise tables for Prosthetic Records. Futoshi Uehara (上原太 , Uehara Futoshi ) , born April 15, 1980 and also known as , is a Japanese bassist and current member of rock band Maximum The Hormone.  He was the last to join the band in replacement of their former bassist "Key" who departed the band in 1999.  He is the youngest member of the band.  Uehara's playing style is highly influenced by Flea, the bassist for the band Red Hot Chili Peppers.  Uehara is characterized by his twangy and heavy slapping and popping bass style, which is unique in nu metal, as it is more of a funky bass playing style.  In many of the band's songs his playing is easily audible over the harsh vocals and guitar riffs.  He plays Sadowsky jazz basses and a Modulus FB4 and also sports tattoos that resemble those of his idol, Flea.  He very rarely sings, but in some songs such as "Houchou Hasami Cutter Knife Dosu Kiri", "Kyoukatsu" and "Nigire Tsutsu", he has provided backup vocals. Jason "Jay" James (born 13 January 1981) is a Welsh musician, singer, songwriter, and bassist.  He is best known for being the former bassist and backing vocalist for the Welsh heavy metal band Bullet for My Valentine from 2003-2015.  He was also a bassist and vocalist for the defunct metal band N.U.K.E. The 20th Anniversary Farewell Tour is a concert tour by former members of Rhapsody.  It was announced on November 21, 2016 by ex-Rhapsody members Luca Turilli (founder and composer), Fabio Lione, Patrice Guers, Dominique Leurquin and Alex Holzwarth.  It will celebrate the 20th anniversary of Legendary Tales and will be having a number of their classic hits played at their shows, along with Symphony of Enchanted Lands in its entirety. SWA (pronounced swǒ) the band originally started as a concept defined by Chuck Dukowski, former bassist of Black Flag while he was still a member of that band.  The name (which is pronounced like "Swah" and not "S-W-A") was created by assigning an alphabetical value to numbers on a gaming die, then rolling the die three times.  Dukowski would later claim that the name was offered up by Joe Carducci and was accepted by the rest of the band, despite Chuck's own discomfort with it.  SWA has had the dubious distinction of being considered the "worst" band to ever record for SST Records by many label aficionados and, in one infamous fanzine article, Steve Albini claimed that among the worst things a person could do was "listen to SWA" and "be SWA".  However, others have come to the band's defense.  The band existed from the mid 1980s until 1992 and released 5 full-length albums on SST Records, all of which are currently out of print. From Chaos to Eternity is the ninth full-length studio album by the Italian symphonic power metal band Rhapsody of Fire.  It was released in June 17, 2011 via Nuclear Blast.  This is the last album to feature long-time guitarist/songwriter Luca Turilli, bass guitarist Patrice Guers, and session guitarist Dominique Leurquin, who all left the band on good terms in August 2011 to found Luca Turilli's Rhapsody, the last album with Christopher Lee as narrator, and the only album with guitarist Tom Hess. Patrice Guers (born 5 September 1969 in Annecy, Haute-Savoie) was the former bassist of the Italian symphonic metal band Rhapsody of Fire.  He joined the band after Alessandro Lotta left the band and performed with them until 2011, when he departed with guitarist Luca Turilli to found Luca Turilli's Rhapsody.  He has also worked with Patrick Rondat, contributing in several albums and live appearances.  He started playing bass at the age of fourteen.  He has a progressive style of playing bass.  Patrice is endorsed by the Vigier Basses company, French manufacturer. Brent Ashley is a bassist who is the current bassist for Combichrist and former bassist for The Natural Born Killers featuring Max Green of Escape The Fate.
