Query: An overdose of heavy psych

Another compilation from this series,features psych from the mid 60s to early 70s.As you would expect from a compilation like this strange group names and awsome music most of the songs featured have an organ in them as well as the fuzz guitar sound.Also comes with brief history of each of the groups featured.Remastering is quite well done even though most of the tracks on here have come from the original 7 inch singles,but don't let this put you off I have found some really good songs on this compilation.Overall a worthwhile buy.
