[Machine Translation] The title tune "Dirty Disco" is a number that celebrates THE RAMPAGE's free STEELO (way of life) over a funky beat rooted in disco music! The groove of the song is a product of the many trials and tribulations the group has overcome together since its formation. The coupling song "Shangri-la" shows a new side of THE RAMPAGE with its catchy and refreshing sound and lyrics that are easy to relate to. The Bonus Track is the English version of the 2nd Single "Frontiers". The DVD includes the title tune "Dirty Disco" and the music video for the dance track "RAMPAGE ALL DAY". RAMPAGE ALL DAY" features a special guest appearance by Japan's leading HIP HOP artist "Zeebra"! Don't miss the dance moves of 13 of THE RAMPAGE's performers!
