Project.R

Project.R is a Japanese musical ensemble established by Nippon Columbia and Toei Company to perform on the soundtracks for the Super Sentai Series beginning with Engine Sentai Go-onger.

For the various series, Columbia has taken various popular vocalists of anime songs and brought them together in a group called Project.R (the "R" stands for "Ranger"). The opening and ending themes as well as the insert songs are all performed by individual members or a subset of members of Project.R. Several songs are performed by long standing theme song singers who are not included as being members of Project.R (the songs are composed by Project.R members, though).
