There is more than one artist with this name:
1) Scooter is a German group, formed by Soren Buehler, Hans-Peter Geerdes, Hendrik Stadler and Jens Thele, in Hamburg in 1994.
Originally the group started as a side project in 1994. Their debut single Vallée De Larmes (French for Valley Of Tears) reached #8 on the German dance chart. In April of that year, Scooter played their first live show in Hamburg, Germany, where vocalist Hans-Peter Geerdes began freestyling off the top of his head to an instrumental dance track. At that point, Scooter officially became a group, and Geerdes' rapping would become one of the band's trademarks together with the fact that they all of their tracks are in fact remixes, though often with different titles than the original tracks.
In 2002, Scooter enjoyed somewhat of a comeback, with 6 top twenty UK singles ('RAMP! (The Logical Song)', 'Nessaja', 'Posse (I Need You On The Floor)', 'Weekend!', "The Night', and 'Maria (I Like It Loud)') all charting in an 18 month period (prior to this comeback, they only ever had one top twenty single in the UK, 'Back In The UK').
They have a sort of 'trademark' style of dance, with most of their songs featuring some "rap shouting", sometimes featuring a high pitched vocal, which is evident especially on their biggest hit 'RAMP! (The Logical Song)' (which samples 'The Logical Song' by Supertramp). Much of their music features elements of a live performance, including the roar of the crowd, and the echoing sound of Geerdes' voice.
Scooter's style would also appear to harp back to that of The KLF, especially so with the track entitled "Posse! (I Need You On The Floor) - with a sample which recurrs throughout the work of The KLF. KLF references are also frequently used in Scooter songs. Both bands have released singles with the title "Fuck the Millennium": KLF in 1997 under the pseudonym 2K, and Scooter in 1999. Relatively lenghty and complex samples used in KLF tracks have often surfaced in Scooter tracks, such as the entire opening seconds of the KLF's 3am Eternal being used to open Hello (Good to be Back) by Scooter.
On September 9th, 2005, Scooter performed their first concert in North America at the Allstate Arena in Chicago, Illinois along with opening acts such as DJ Markski (Chicago), DJ Erikk, Aquagen, and Benassi Bros. It was here that the latest single at the time 'Hello! (Good To Be Back)' was played to the public for the first time.
Most recently Scooter went on their latest tour entitled 'Who's Got The Last Laugh Now?' Tour 2006, named after the latest studio album. After the tour they released a CD and 2 disc DVD entitled 'Excess All Areas', containing the final concert of the 2006 tour on one disk, and every single video for every single release on the other.
Following the success of the jumpstyle anthem "The Question Is What Is The Question?", top ten hit number 20 for the band, the 18th album "Jumping All Over The World" by the Hamburg combo was released in April 2008. It was their first album release for 5 years in the UK yet went in straight at number 1, displacing Madonna's 'Hard Candy'.
Autumn 2008. Big music cooperation between Scooter and classic rock legends - Status Quo. They release together new single Jump that Rock.
In 2009 Scooter have continued to grow under All Around The World. They released J'Adore Hardcore, followed by their second studio album Under The Radar, Over The Top.
2) Scooter is a Belgian 80's band, known by their hit single 'You' (voted for being the best Belgian production of 1981).
