This site is an attempt to document worldwide heavy psych, hard rock, proto-metal, etc. 45s recorded from 1967-1977. Obviously there is a large amount of subjectivity involved in determining what fits this criteria and what does not. Here are some guidelines I try to follow to keep this project bounded:
-Records with a straight “garage” sound are excluded. This is probably the most nebulous of the criteria, and when in doubt I tend to err on the side of inclusion. The idea though is that garage rock 45s have been extremely well-documented elsewhere, and I don’t intend to duplicate the hard work of others.
-Records that are too keyboard-heavy or “proggy” are excluded.
-Records that are too far in the realm of “blooz rock boogie” are excluded.
-Records with tracks that appear on LPs are excluded. This includes edits!

So everything else that fits my admittedly somewhat arbitrary definition of “heavy” is included. Of course not every record listed on this site actually plays at 45RPM, but the term “45″ transcends its literal definition in the record collecting world.

I wanted to include some measure of a record’s rarity or value. But the primary purpose of this site is not to become a price guide (and precise values are often difficult to determine with any measure of accuracy), so I have included a scale from 1-5 stars, with the breakdown as follows:
– indicates a typical value in the range of $0-$49 (US).
– indicates a typical value in the range of $50-$99 (US).
– indicates a typical value in the range of $100-$249 (US).
– indicates a typical value in the range of $250-$499 (US).
– indicates a typical value of $500+ (US).
