 The N.W.O.B.H.M. Encyclopedia by Malc Macmillan lists more than 500 recording bands established in the decade between 1975 and 1985 and related to the movement. Probably as many bands were born in the same time interval, but never emerged from their local club scene, or recorded nothing more than demos or limited pressings of self-produced singles. The disinterest of record labels, bad management, internal struggles and wrong musical choices that turned off much of their original fan base, resulted in most groups disbanding and disappearing by the end of the decade. A few of the best known groups, such as Praying Mantis in Japan and Saxon, Demon and Tokyo Blade in mainland Europe, survived in foreign markets. Some others, namely Raven, Girlschool and Grim Reaper, tried to break through in the US market signing with American labels, but their attempts were unsuccessful.
