‘Esperanto’ was composed for a performance by New York avant garde choreographer Molissa Fenley. Produced and performed by Sakamoto with contribution by Arto Lindsay and Japanese percussionist Yas-Kaz, "Esperanto" originally came out in 1985 and was Ryuichi Sakamoto's sixth solo album.
It is composed of eight tracks displaying a varied mix of influences. "A Wongga Dance Song" comprises pulsating rhythms while "A Rain Song" adopts a minimalist mode with its distinctive repetitive patterns. "Dolphins" and "A Carved Stone" are captivating ambient pieces showcasing Sakamoto's talent for setting beautiful abstract melodic ornaments over atmospheric tones.
One of the highlights of the album is "Adelic Penguins", a fascinating proto techno piece with a funky twist stretching over six minutes which echoes the electro funk of 1981's album "Hidari Ude No Yume." "Ulu Watu", a collage-like piece featuring bird motives and a tropical soundscape closes the album with an experimental note.
