Problem: The Spice Girls are an English pop girl group formed in 1994. The group originally consisted of Melanie Brown ("Scary Spice"), Melanie Chisholm ("Sporty Spice"), Emma Bunton ("Baby Spice"), Geri Halliwell ("Ginger Spice"), and Victoria Beckham, nee Adams ("Posh Spice"). They were signed to Virgin Records and released their debut single "Wannabe" in 1996, which hit number one in 37 countries and established them as a global phenomenon. Their debut album Spice sold more than 31 million copies worldwide, becoming the best-selling album by a female group in history.

The phrase "girl power" put a name to a social phenomenon, but the slogan was met with mixed reactions. The phrase was a label for the particular facet of post classical neo-feminist empowerment embraced by the band: that a sensual, feminine appearance and equality between the sexes need not be mutually exclusive. This concept was by no means original in the pop world: both Madonna and Bananarama had employed similar outlooks. The phrase itself had also appeared in a few songs by British girl groups and bands since at least 1987; most notably, it was the name of British pop duo Shampoo's 1996 single and album, later credited by Halliwell as the inspiration for the Spice Girls' mantra.  However, it was not until the emergence of the Spice Girls in 1996 with "Wannabe", that the concept of "girl power" exploded onto the common consciousness. The phrase was regularly uttered by all five members--although most closely associated with Halliwell--and was often delivered with a peace sign. The slogan also featured on official Spice Girls merchandise and on some of the outfits the group members wore. The Spice Girls' version was distinctive. Its message of empowerment appealed to young girls, adolescents and adult women, and it emphasised the importance of strong and loyal friendship among females.  In all, the focused, consistent presentation of "girl power" formed the centrepiece of their appeal as a band. Some commentators credit the Spice Girls with reinvigorating mainstream feminism--popularized as "girl power"--in the 1990s, with their mantra serving as a gateway to feminism for their young fans. On the other hand, some critics dismissed it as no more than a shallow marketing tactic, while others took issue with the emphasis on physical appearance, concerned about the potential impact on self-conscious and/or impressionable youngsters. Regardless, the phrase became a cultural phenomenon, adopted as the mantra for millions of girls and even making it into the Oxford English Dictionary. In summation of the concept, author Ryan Dawson said, "The Spice Girls changed British culture enough for Girl Power to now seem completely unremarkable."  The Spice Girls' debut single "Wannabe" has been hailed as an "iconic girl power anthem". In 2016, the United Nations' Global Goals "#WhatIReallyReallyWant" campaign filmed a global remake of the original music video for "Wannabe" to highlight gender inequality issues faced by women across the world. The video, which was launched on YouTube and ran in movie theatres internationally, featured British girl group M.O, Canadian "viral sensation" Taylor Hatala, Nigerian-British singer Seyi Shay and Bollywood actress Jacqueline Fernandez lip-syncing to the song in various locations around the world. In response to the remake, Beckham said, "How fabulous is it that after 20 years the legacy of the Spice Girls' girl power is being used to encourage and empower a whole new generation?"  At the 43rd People's Choice Awards in January 2017, American actress Blake Lively dedicated her "Favorite Dramatic Movie Actress" award to "girl power" in her acceptance speech, and credited the Spice Girls, saying: "What was so neat about them was that they're all so distinctly different, and they were women, and they owned who they were, and that was my first introduction into girl power."

Question:
The Wallflowers are an American rock band formed in Los Angeles in 1989 by singer-songwriter Jakob Dylan and guitarist Tobi Miller. The band has gone through a number of personnel changes but has remained centered on Dylan. After releasing their eponymous debut album in 1992, the Wallflowers released what would become their best-known and highest-selling album, Bringing Down the Horse in 1996, which featured songs such as "One Headlight" and "6th Avenue Heartache". They went on to release an additional three albums before going on a seven-year hiatus, beginning in 2006.
In July 2004, the Wallflowers returned to the studio to record their fifth album, Rebel, Sweetheart. This time the band decided to record in Atlanta, Georgia, which is where their producer for this album, Brendan O'Brien, is based. O'Brien also contributed on guitar. Fred Eltringham joined the Wallflowers as their new drummer. Jakob Dylan wrote the songs, of which keyboardist Rami Jaffee has said: "What I did notice is that kind of upbeat song with some pretty scary lyrics." Dylan painted the album's cover art himself.  On October 14, 2004, the Warren Zevon tribute album Enjoy Every Sandwich: The Songs of Warren Zevon was released, on which the Wallflowers covered Zevon's 1978 song "Lawyers, Guns and Money." In promotion of the album, the Wallflowers performed "Lawyers, Guns and Money" on the Late Show with David Letterman with Zevon's son, Jordan, on October 12, 2004.  On October 31, 2004, the Wallflowers were flown via military transport plane to the USS John C. Stennis aircraft carrier in the middle of the Pacific Ocean to perform for the returning troops.  Rebel, Sweetheart was released on May 24, 2005, and was met with positive reviews. Despite widespread critical acclaim, Rebel, Sweetheart performed relatively poorly commercially, peaking at No. 40 on the Billboard 200. However, the first single from the album, "The Beautiful Side of Somewhere", hit No. 5 on AAA radio. The second single was "God Says Nothing Back". This was the first Wallflowers album to be released on DualDisc. On one side was the album, and on the other was a DVD that included exclusive performances and arrangements of some of the band's songs, as well as an interview with comedian Jon Lovitz. In promotion of the album, the Wallflowers did concerts for the Oxygen Custom Concert Series and PBS Soundstage. Around the time of the album's release, the band set out on what would be their last tour for two years. They were joined by Stuart Mathis on lead guitar. After 2005, the Wallflowers ended their relationship with Interscope Records.
