This is a mashup of two versions of "ECHO" by Crusher-P, the original & an alternate vocal mix ( https://soundcloud.com/ew_fee // https://www.youtube.com/watch?v=CUPHqhotql0 ). Side A pitches the alternate up 2 semitones to match the original. Side B pitches the original down 2 semitones to match the alternate. Side C pitches the alternate up 1 and the original down 1 to meet in the middle. Side D slows a prior mix down for a different feel. I do not own this track. These mashups were done for non-profit fun and to enjoy the music in a new way. Visuals were used from the original's uploads and a fan-made animation by v0idless. Have a great day.
