Wikipedia:Articles for deletion/Complex (English band)
The band has https://disquesobscurs.fr/2018/09/complex-complex-1971/ an extensive profile on the French Website disquesobscurs.fr. ''Disques Obscurs'' appears to be a pass for  as it has https://disquesobscurs.fr/cest-quoi-ce-site/mentions-legales/ an editorial team and professional reviewers. The Blackpool Gazette profiled this band in 2013, though they have now deleted the article from their website it was https://web.archive.org/web/20130907064707/http://www.blackpoolgazette.co.uk/what-s-on/music-dance/we-looked-at-each-other-thinking-this-lad-s-good-1-6017852 archived here. Record Collector Mag briefly reviewed one of their albums here - short but it does https://recordcollectormag.com/articles/200-rarest-uk-albums at least list the band members. The French book "Encyclopédie du hard-rock des Seventies" by Denis Protat appears to come from a professional publishing company called ''Editions Alternatives'' (i.e., is not self published) and lists their albums with a fairly long review of their second album, the text of which can be seen https://archive.org/stream/DenisProtatEncyclopedieDuHardRockDesSeventies2004/Denis%20Protat%20-%20Encyclopedie%20Du%20Hard-Rock%20Des%20Seventies%20%282004%29_djvu.txt here. Appears to be a pass for  no. 1, specifically reliable sources are still talking about this band as notable some decades after their career
