Aguaturbia is a Chilean band formed in 1968 and disbanded in 1972. "Psychedelic Drugstore" is actually a compilation of their two albums ("Aguaturbia" and "Volumen 2"). From what I found its release date is 1993 but I'm not sure about it. No matter what, these songs were recorded 40 years ago and they're still fuckin' brilliant.
I mean listen to "Rollin' n' Tumblin" and "Heartbreaker". Or "Waterfall". Absolutely excellent heavy blues rock in Blue Cheer's paths. Don't let female vocals mislead you that they're moving in softer waves. They're groovy, they have soul, they totally rock. In music's overall feeling you can see influences of what US psych scene has offered.
Indisputably they were one of the leading underground acts in South America's scene at this point and this is their testament which I believe you should check out.
