DIASS masters of your mind 25BLP-001

Unearthing the Underground: Diass’ ‘Masters Of Your Mind’ (25BLP-001)

Today’s entry takes us into the Japanese underground heavy metal scene of the late 1980s with the album “Masters Of Your Mind” by the band Diass, released on Black Box Records with the catalog number 25BLP-001.

Issued in 1988, this 12-inch vinyl LP represents the work of a band operating within the fertile independent metal scene of that era. Black Box Records was an indie label known for releasing material from bands outside the major system, often capturing a rawer and more aggressive sound.

“Masters Of Your Mind” delivers a potent dose of late 80s Japanese metal, blending elements of heavy metal, power metal, and potentially thrash. Listeners can expect energetic and aggressive guitar riffs, powerful vocals (likely in the higher register common for the style), driving rhythms, and the raw intensity characteristic of underground releases from the period. Diass existed within the vibrant network of bands playing the live house circuit, contributing their own flavor to the diverse metal landscape.

For collectors of rare Japanese metal and enthusiasts of the 80s underground scene, 25BLP-001 is a significant find. It documents a band contributing to the heavier end of the spectrum during that period and represents the output of the independent Black Box label.
