This Japanese pop band started in the late 80’s.
They originally had three members – Miwa Yoshida singing, Masato Nakamura on bass and Takahiro Nishikawa on keyboard.
Masato and Miwa started the band and Takahiro joined but then left in 2002.
Japan loves shortening words
(like sandwich/サンドウィッチ turning into sand/サンド… which sounds much less appetizing).
So, the band is commonly known as DCT and sometimes even more compounded Dorikamu/ドリカム.
The J-pop duo have sold over 50 million records.
