This is the standard soundboard sound source of the California Jam performance on April 6, 1975, when Black Sabbath was at its peak, recognized by the members. California Jam is also known for broadcasting Deep Purple and EL&P. This is a high-quality sound source that has recently been released from the reel tape of a microphone placed on an amplifier on stage, but unlike that, this is a refined version of the legitimate "line recording" that has been heard for a long time. It is a thing. The distortion is suppressed and the sound is more direct than the previous one, making it a piece that allows you to directly enjoy the explosive sound of the time.
