For a long time, I couldn't find any Jack Costanzo records. Then I found 2 within about a month. I think this is called Vinyl Karma*

The Mysteries of Record Hunting
  Everywhere you go, you can find most  of the 148 recordings Ferrante and Teicher released, except for these two:
Blast Off and Soundblast.  I was lucky enough to find a couple of copies of Soundproof, which is among my top 10 favourite record covers.
The strange thing about record hunting and collecting is that I have found records I've been looking for for a long time in a just a short period of time.  For example, Jack Costanzo LPs appeared within a couple of weeks of each other and I'd been looking for what seemed like forever for them.
Other examples are: Saying out loud that I wanted to find some Patti Smith on vinyl, only to find "Horses" the next week. This also happened with X after I once again said out loud I wanted to find some X.  Is is just good luck or karma? Who knows.....  But I keep saying out loud that I want Frank Comstock's "Music From Outer Space" but nothing happens. 
   So now we know that Ferrante and Teicher have released 148 mostly forgettable LPs save a few records.  But how the heck do you pronounce their names?  And why the hell can't I find copies of Soundblast and Blast Off, but see all their others everywhere I go?
Karma! It's karma, I tell you!

Other mysteries are that you could go weeks without finding anything new to add to your collection and then all of a sudden, you find 20 records you've never seen before.  I call the dry spells the "doldrums."
Sometimes, when friends tell me what they've found locally, I mentally kick myself, thinking "If only I'd gone to such and such that day
I would have found it!"  But then I too brag about my scores so maybe others think the same way about me.  And I am still puzzled by the people who donate these old records to thrift stores.  I mean, what are they thinking to dump off those near mint copies of Esquivel's Infinity In Sound or Music For Big Dame Hunters with Irish McCalla on the cover? Maybe they're thinking, let's get rid of this old crap nobody wants!
