The eponymous album was very progressive, blending improvised prog-rock and psychedelic jazz fusion with strong ethnic flavors. Seven band members imitated sounds of traditional Turkmen instruments, such as dutar, dili tuiduk, and g'ijjak, on regular keyboards, guitars, saxophone, flute, and violin.
As an instrumental group, especially with a favorable image of a "national ethnic ensemble from one of the Soviet republics" (hence the band members wearing traditional telpek fur hats on the cover), Firyuza got a pass on censorship and were provided with a full artistic freedom. Just the fact that the album has a classic prog-style format with only four 8-min tracks is noteworthy enough for a record released in USSR in the 1970s.
The record was pressed in Tashkent, at the plant which had been producing some of the smallest Melodiya editions, and never got re-issued. That's why original copies in decent condition are very rare nowadays, bumping the price up to $500-600 and making Firyuza one of the "holy grails" of Soviet psych jazz from Central Asia among Western record collectors, together with Gunesh and Dos-Mukasan LPs.
In 1980, the band also released a split tape with Gunesh (Melodiya, CM 00833), which included three tracks from the album. "Firyuza" was placed on a list of 50 vinyl records to be re-released as a part of 50-th Melodiya anniversary in 2014.
