Problem: Background: The Riddler (Edward Nigma) is a fictional supervillain appearing in American comic books published by DC Comics, commonly as an adversary of the superhero Batman. The character made his first appearance in Detective Comics #140 (October, 1948) and was created by Bill Finger and Dick Sprang. Depicted as a Gotham City criminal mastermind, the Riddler takes delight in incorporating riddles and puzzles into his plots, and leaves them as clues for the authorities and Batman to solve. The character is one of Batman's most enduring enemies and belongs to the collective of adversaries that make up Batman's rogues gallery.
Context: The Riddler makes his first true appearance in the new DC continuity relaunch, DC Rebirth, in Batman #19. An inmate of Arkham once again, he rather cooperatively assists Bane in unlocking a high tech door, allowing Bane access to confront Batman.  In the eight-part story-arc "War of Jokes and Riddles", commencing with Batman Vol. 3 #25, flashbacks to a year after the events of "Zero Year" have Batman recounting the details of a war between Riddler and Joker. He is first seen in custody at the GCPD, assisting them in solving a variety of crimes, including locating Joker's whereabouts, before stabbing a police officer to death 26 times. Blackmailing the approaching guards with details of their children and families, Riddler walks out freely before intruding into Joker's office. Riddler seemingly offers the Joker a partnership, acknowledging that if either of the two men individually kill Batman, the other will be left forever unsatisfied. However the Joker shoots Riddler in the stomach and quickly departs, Batman appearing through the window and giving chase. Left in a pool of his own blood, Riddler rose to his feet and limped out of the office, seemingly unfazed.  Edward quickly healed from the wound, carving a question marked shaped scar over the wound, before murdering Dr. Jaime Knowles. Riddler is then seen meeting with Poison Ivy, discussing the Joker's need to rid anyone who could potentially kill Batman before him. The duo are then ambushed by gunmen working for Carmine Falcone under the orders of the Joker to kill Riddler within the hour. However Poison Ivy attacks the gunmen with her vines, allowing Edward and herself to leave.  Riddler eventually formed his team, consisting on himself, Poison Ivy, Scarecrow, Deathstroke, Clayface, Killer Croc, Two-Face, Firefly, and Victor Zsasz. Waging war on Joker's team across Gotham, Riddler is responsible for poisoning Charles Brown's son, resulting in his transformation into Kite Man who joins up with Joker's team consisting of Cluemaster, Deadshot, Mad Hatter, Man-Bat, Mr. Freeze, Penguin, Solomon Grundy, and Ventriloquist. The war continues, with Riddler and Joker claiming territories across Gotham, before Riddler, who'd convinced Batman to side with him during the conflict, blackmails and interrogates Kite Man into giving up Joker's location. However Batman, after a brief fight between him, Riddler and Joker, becomes disgusted by Riddler's actions and quickly grabs a blade, breaking his one rule of No Killing in order to stab Riddler. However Joker, who finally begins to laugh again, prevents Batman from doing so.  The present day Riddler shows up next in 'Deathstroke #25' as a member of The Society who have placed Deathstroke on trial for appearing to have reformed. Riddler, using Hector Hammond's abilities, convinces the Society that Deathstroke is indeed evil by showcasing a simulation of Deathstroke killing them all right before Deathstroke himself is kidnapped.

Problem: Background: Spacemen 3 were an English alternative rock band, formed in 1982 in Rugby, Warwickshire by Peter Kember and Jason Pierce. Their music is known for its brand of "minimalistic psychedelia". Spacemen 3 had their first independent chart hits in 1987, gaining a cult following, and going on to have greater success towards the end of the decade. However, they disbanded shortly afterwards, releasing their final studio album post-split in 1991 after an acrimonious parting of ways.
Context: Most members of Spacemen 3 have continued to produce music and record either collaboratively or in solo projects. Peter Kember (alias 'Sonic Boom') has had a solo career releasing music under the monikers Spectrum and E.A.R., and has also done production work for MGMT, Panda Bear, Dean & Britta and The Flowers of Hell. Jason Pierce (alias 'J. Spaceman') remains the leader and creative force, and only constant member, of the alternative band Spiritualized who have achieved significant critical acclaim and commercial success. Both Kember and Pierce continue to perform some Spacemen 3 songs live (e.g. "Transparent Radiation", "Revolution", "Suicide", "Set Me Free", "Che" and "Let Me Down Gently" [Kember]; and "Take Me to the Other Side", "Walkin' with Jesus", "Amen" and "Lord Can You Hear Me?" [Pierce]).  Will Carruthers, Jonny Mattock and Mark Refoy formed Spiritualized with Pierce in early 1990. Carruthers left the band after the first album in 1992; followed by Mattock and Refoy in 1994. Refoy then fronted Slipstream who released two albums. Refoy played guitar for the Pet Shop Boys on their live tour in 2007. Will Carruthers took a hiatus from the music industry after leaving Spiritualized; but subsequently has worked with Kember, recorded two solo albums as Freelovebabies, and has most recently toured with The Brian Jonestown Massacre. Carruthers, Mattock and Refoy have also collaborated on projects together.  After leaving Spacemen 3 in 1988, both Pete Bain and Stewart Roswell ('Rosco') joined the neo-psychedelic band Darkside who released several albums. Following the end of Darkside, Bain formed 'Alphastone', and has assisted Kember on some of the latter's solo projects. As of 2010 he provides vocals and guitar in 'The Urgz'. Stewart Roswell (alias Sterling Roswell) released a solo album, The Psychedelic Ubik, in 2004.  In the early 1990s, early Spacemen 3 drummer Natty Brooker played bass under the alias 'Mr Ugly' in Garage rock band 'The Guaranteed Ugly', with Gavin Wissen. They released two albums. Brooker provided cover artwork for Spacemen 3's Recurring album and early Spiritualized releases. Brooker died of cancer on Friday 18 April 2014.

Jason Pierce (alias 'J. Spaceman') remains the leader and creative force, and only constant member, of the alternative band Spiritualized who have achieved significant critical acclaim and commercial success.
