"This electropop duo who are sometimes referred to as "SOCOPO" could be described as cute super hyper insanity. Formed back in 1999 by Chinatsu Furukawa and Akira Suzuki (the owner of USAGI-CHANG RECORDS), Sonic Coaster Pop has released countless releases, participated in numerous compilations and done remixes for just about everybody. The group originally made their indie debut on LD&K Records in 2000, but departed when Akira formed USAGI-CHANG RECORDS in 2002. From that point on they produced some of the most famous electro pop albums in Japan."

Zac Bentz from ZB's A-Z of J-music had this to say about them:

" Sonic Coaster Pop are a chiptune/sugary electro pop hybrid. Think YMCK meets Perfume. They offer up a relentless mix of up-tempo, super positive songs, suitable to be the muzak in shopping complexes of the future. While the singing may be a bit shaky at times, the layers of sparkley effects help to mask any sense of real humanity." Read more on Last.fm.
