Frehley and Criss did well despite the mistreatment and purposely being unacknowledged, earning fortunes anyway due to the massive amount of money KISS earned over the years as an entity, enterprise and cultural phenomenon. The four solo album project was meant to prove that the founders' popularity far outstripped that of "the help" - and it hilariously blew up in Simmons' and Stanley's faces.
Ace was never the greatest guitarist nor known for innovation like Clapton or Page, but he was a trooper who dutifully played thousands of shows in uncomfortable make-up and costumes; often risking injury due to pyrotechnics, stunts and the vices that plague rock stardom. Thank you, sir.
If you only know his work from his time with KISS please listen to this instrumental, "Fractured Mirror", from that solo album.
(Truly great astronomy photographs in the video for you cosmological compatriots.)
Instead of listening on my tablet, I went to YouTube on my 55”, put on my Bluetooth headphones, and hit play. I saw another video with some other music of his named Fractured III. Space Station footage set to music- awesome. Thanks for pointing it out, I added it to my playlist.
