The Party Animals made their introduction on the video for the single “I Wanna Be a Hippy” by Technohead. The clip featured three gabbers and a hippie. Flamman & Abraxas discovered the four and saw a potential for opening the mainly underground scene of gabber by making the sound more pop-oriented and thus introducing the new genre to a mainstream audience.

The first single was “Have You Ever Been Mellow” which samples Olivia Newton-John’s “Have You Never Been Mellow” The lyrics still contain parts of the original song with “Never” replaced by “Ever”. Released in September 1995, it took three months before becoming a number 1 hit.
In 1997, Flamman & Abraxas formed a one-time spinoff group called the “Mini Animals”, consisting of four boys aged 10 to 13. They only released one EP, titled “Get Up, Stand Up!” before the group disbanded. However, two of the Mini Animals, Youri and Jordi, would later officially join the Party Animals in 2002.

The group disbanded in 2000 after considerable success in the Netherlands and a hit in Hong Kong with “Atomic”.

The group reunited in 2002 after they were re-discovered at a student party in Delft. After Jeroen Flamman discovered how popular the Party Animals’ singles still were, he decided to revive the group. As a result, “Life Was Short” was released in 2002 and “Xanadu” followed in 2003. The group’s fourth studio album, Gang of 4, was released in 2004.

In 2014, their fifth studio album, Greatest Hits and Underground Anthems, was released, which contained a new track titled “This Moment”.
