Question: Which band was formed first, Goldfinger or Poster Children?

Context paragraphs:
Five Style: Five Style (a name taken from a martial arts technique called "Five Style Fist"), also known as 5ive Style, is a Chicago-based funk/jam quartet.  Their albums were released on the Subpop label in the 1990s.  The group existed from about 1993-2000 in various incarnations, centered on the guitar work of Billy Dolan (who has also played in Heroic Doses, and The Fire Theft which featured 3 members of Sunny Day Real Estate, among other projects).  Other members were major players of the 1990s Chicago music scene and included bassist Leroy Bach (of Chicago funk group Uptighty, the first Liz Phair studio band, and Wilco fame), drummer John Herndon (aka "Johnny Machine", who made his first appearances on record in "Tool of the Man" era Poster Children and became established as a longstanding drummer/percussionist in Tortoise), and keyboardist Jeremy Jacobsen (also known as The Lonesome Organist and member of Euphone).  Drummer Ryan Rapsys, also of Euphone and Gauge, filled in on drums on a January 2000 tour when they opened for Giant Sand and Vic Chesnutt.  5ive Style were the opening act in a brief May 1996 tour which also included The Sea and Cake and Tortoise; by some accounts these dates were the best shows of the Chicago "post-rock" hey day.

No More Songs About Sleep and Fire: No More Songs About Sleep and Fire is the eighth album by American alternative rock band Poster Children, released in 2004.  The version released on enhanced CD-ROM features a layered front cover design, and is enhanced with the video for Western Springs.  The CD-ROM also features an album-length commentary track, which is one of the first ever recorded for a non-visual medium.  The vinyl issue features an exclusive lyric sheet.

Absinthe Blind: Absinthe Blind was an American Shoegaze and Dream pop group from Urbana, Illinois.  The first group was formed by brothers Seth and Adam Fein and Tristan Wraight in 1996, by merging Adam Fein's group (coincidentally also called Absinthe Blind) and Tristan Wraight and Seth Fein's The Dr. Johanson Band.  Dr. Johanson Band bassist Mike Zolfo was then asked to join the group.  As the Champaign-Urbana music scene gained national attention, due to groups such as Hum and Poster Children, Absinthe Blind, along with three other groups, formed a collective entitled Toast Music.  The brothers' younger sister, Erin Fein joined the band during the recording of "Music for Security" while she continued to study sociology and political science at the University of Illinois.  In support of Music For Security, the band embarked on a national tour, performing at The CMJ Music Marathon along the way.  For their fourth album, The Everyday Separation, the band signed to Mud Records, distributed by Parasol.  Zolfo left the group in 2002 to attend music school, and was replaced by Brett Sanderson.  The group released one more album, Rings, in 2003, before Adam Fein announced that he was leaving the band.  A farewell tour followed, culminating with a hometown show at the Canopy Club in Urbana, Illinois on September 13, 2003.

Poster Children: Poster Children is an American indie rock band formed at the University of Illinois at Champaign-Urbana in 1987.  They have issued eleven studio albums.  Known for their strong DIY ethic, the band members continue to drive their own tour bus, create their own artwork and T-shirt designs, and operate their own record label.  Poster Children were also pioneers in several forms of electronic technology relating to performance art, including enhanced CDs, webcasts, and blogs.

New World Record: New World Record is the sixth album by American alternative rock band Poster Children, released in 1999.  This was the first album recorded in their very own studio, Tedium.

Daisychain Reaction: Daisychain Reaction is the third album by American alternative rock band Poster Children.  It was originally released in 1991 on Twin/Tone Records, and reissued by Sire/Reprise in 1992.  It is currently out of print.  The album also spawned the band's first-ever music video, for "If You See Kay".

Goldfinger (band): Goldfinger is an American rock band from Los Angeles, California that formed in 1994.  The band is widely considered to have been a contributor to the movement of third-wave ska, a mid-1990s revitalization in the popularity of ska.  However, the releases of "Open Your Eyes" and "Disconnection Notice", have been more commonly placed as punk rock genre.  Apart from the band's music, Goldfinger is also noted for their political activism, particularly in the area of animal rights.

National Skyline: National Skyline is an American alternative rock band formed in late 1996 by Jeff Dimpsey of Hum.  Dimpsey originally formed the band in order to perform a 45-minute-long song that he had written.  They were initially an indie rock supergroup of sorts, with a rotating cast of prominent Champaign/Chicago area musicians.  They did record the 45-minute song/album with Rick Valentin (of The Poster Children) in spring 1997, but it has never been released.  The band's name is apparently a reference to Bob Dylan's album "Nashville Skyline", though their music betrays no stylistic debt to Dylan.

Tool of the Man: Tool of the Man is the fourth album by American alternative rock band Poster Children, released in 1993.  The title of the album comes from graffiti written in dust on the band's van during the South by Southwest Festival: "Poster Children, Band of the Year, Tool of the Man".  The album art consists of several optical illusions, including an afterimage of the United States flag on the front cover.

Flower Plower: Flower Plower is the first studio album by the rock band Poster Children.  Recorded in 1988–89, it was first released on vinyl by the Limited Potential label in 1989, and reissued on CD in 1991 by Frontier Records.  Later the band acquired the rights to this album, and reissued it on their own label, 12 Inch Records, in 1999.
