I
think this artist is a duplicate of
this one, unless there are two Hiroshi Takeyasus who are Bemani composers. (I mean there very well could be, I am far from an expert on this topic.) No idea where the 竹安宏 writing originated, if it's a mistake, but it's not uncommonly reported among Japanese VGM CD retailers. 竹安弘 is apparently correct, though, for the Hiroshi Takeyasu who had music in the very first beatmania game and is a sound producer.
