I don't know if this is news to anyone other than me. My first experience with Sun Ra was through the CD reissues on evidence. I didn't really keep track of how many had been issued on Impulse, though I've pretty consistently enjoyed everything I've heard on Impulse.
The other day I discovered this amazing site--http://www.jazzdisco.org/impulse-records
It's the entire discography of Impulse and lets you sort by artists. Unfortunately you can not sort by Sun Ra, but nothing on the internet can withstand the mighty power of Control+F.
All of the following were reissued (back in the 60's) on vinyl by impulse (a lot of the titles abridged):
Atlantis
Nubians
Magic City
Angels & Demons
Astro Black
Jazz in Silhouette
Fate in a pleasant mood
Supersonic Sounds
Bad & beautiful
Space is the Place
Now check out all these albums that Impulse planned to release (but never did):
Night of purple moon
Visits planet earth
My brother the wind (I'm assuming volume 1 which I still haven't heard)
Sound Sun Pleasure
Cosmic Tones
Travel the spaceways
Other planes
Art forms
Monorails
Cymbals
Crystal Spears
Pathways to unknown worlds
It's probably my fault for not reading all the evidence sleeves, but I had no idea that so much had come out on Impulse, and so much more should have come out on impulse. It seems strange that reissuing them on CD was done by a label other than Impulse, but perhaps there was some falling out between Sun Ra and Impulse? I'll leave this one to you Sun Ra detectives for the time being.
I know this isn't about Sun Ra, but it is ALMOST as important. Took some photos of a homebrew Dogfish Head 90 min IPA clone (extract).
