Across time and beyond genre, this is an audio component test record that continues to earn universal acclaim. Drop the needle and unleash the fateful grooves etched into its tracks.

The rediscovery of this album—originally produced as a test record for high-end audio systems—stands as one of the great rewards brought about by the rare groove movement. The project was led by the visionary Katsunori Ishida, who would later become renowned as a producer, composer, and arranger for numerous television and film soundtracks. Gathering an exceptional line up of musicians including Shuichi “Ponta” Murakami, Akira Okazawa, Mikio Masuda, Kenji Ohmura, and Tantan, Ishida crafted a sound that is both tight and sophisticated.

Tracks such as “Cool Head” and “Son Of Pin Head” showcase grooves that are at times as powerful as a hammer blow, and at others as thrilling as a rushing torrent. The musicianship, precision, and dynamic energy throughout are simply outstanding. Today, thanks to its remarkable level of craftsmanship and commanding presence, this album is recognized as a true masterpiece, admired and celebrated far beyond the boundaries of any single genre.
