Transformers VSY Grimlock VS Soundwave Audio Cassette

Originally given away with the Transformers VSY gift set in Japan along with the figures of Grimlock and Soundwave this audio cassette contains a very brief story of a battle between the pair. I don't have the original cassette as the gift set is very pricey but it was included on the Destron Laserdisc CD which is fully available in the music section.
