After the great sucess of the three Andergraun Vibrations vinyl comps (all sold out except the recently issued Volume 3), we present the second CD on Hundergrum Records, which contains the second side of the long out of print Volume 2 LP ("Psychedelic Hard-Rock from Spain 1970-78") and Volume 3 LP ("Spanish Psychotronic Brain Damage 1967-75") in its entirety. 18 ultra-rare tracks taken from mostly small and private labels. We've included even a few South-American artists which recorded in Spain at the time. From wild garage-psych to primitive hard-rock and exploito psych, it's all here! You'll find the rarest Spanish groove-psych library record ever (two copies known!), "L.S.D" by Mario Selles Orchestra ripping Hendrix sounds by Jordi "Toti" Soler from his unknown private pressing second solo 45, fuzz-wah madness a la Stooges by Pinonate, acid sixties-punk by Los Crich, trashy prog sounds by Colores, basement hard-rock insanity by Prou Matic (taken from their impossible to find flexi-disc), exploito fuzz by The Matches, raw garage fuzz by the The True, rural garage psych by Los Riscos, lo-fi underground proto-punk sounds by Vibracion (only two known copies of their 45), a five minute deconstruction of "(I can't get no) Satisfaction" by prog band/commune Franklin, trashy hard-rock by Luis Queimada and Argentinian band Katunga, killer psychedelic hard-rock loaded with trippy efects by Cuban born musician Chirino, wild female hippie sounds by Norah... Features carefully remasterd sound, an amazing full-colour 28 page booklet with detailed and updated liner notes in English/Spanish about each band and rare pictures, most of them taken from the archives of the bands involved.
