Amazing collaboration of talent here with Marian Varga of Collegium Musicum and famed guitarist Pavol Hammel joining forces. The outcome, to little surprise, turned to be a one of the finest Czechoslovakian progressive albums during the early seventies. Rare and recomended. 1st pressing with white/red Opus labels and gatefold cover. Condition is weak EX with faintest superficial scuffs but great play, cover with lightest wear on corners and opening.
