Corgan released a statement on Friday (04Dec15) after waking to the sad news of his peer's passing and feeling "compelled to put pen to paper and pay my respects to Scott".
"I will not pretend to know more than I know, or add some sad homily to how he loved his life," the rocker wrote. "At least in that, may I now say he is undoubtably (sic) in the arms of grace and eternal love. May I also offer my humble condolences to his family, friends, and band mates; who have, and are, suffering this great loss. For when anyone as vaunted leaves far too soon, we mourn all that might have been."
The Smashing Pumpkins star added, "As any fan, I find myself reflecting on what I do have in my own treasure chest: in scarce moments where Scott and I spoke as contemporaries or competitors, and got to know each as people other past the footlights and shadows we were so busy casting to the world.
"It may seem trite in reflection, but I'd try to make him giggle when I saw that the manic whirl of the dumb parties we were at (in Hollywood, no less!) might be causing undue stress. It was, I'd guess you'd say, my way of apology for having been so critical of (his band) STP (Stone Temple Pilots) when they appeared on the scene like some crazy, man-fueled rocket.
"Not only was the knight up front freshly handsome to a fault, but he could sing too! As any supreme actor gives a real and different voice to each character played.
"It was STP's third album that had got me hooked, a wizardly mix of glam and post-punk, and I confessed to Scott, as well as the band many times, how wrong I'd been in assessing their native brilliance. And like (David) Bowie can and does, it was Scott's phrasing that pushed his music into a unique, and hard to pin down, aesthetic sonicsphere."
Corgan ended his statement with a note of high praise, suggesting Weiland and other tragic rockers Layne Staley and Kurt Cobain were "the great voices of our generation".
He ended by writing, "So it goes beyond tragedy to say it is we who lost them, and not the other way round..."
Weiland, 48, was found dead on his tour bus in Minnesota on Thursday night (03Dec15). Reports suggest he passed away in his sleep before a show with his band The Wildabouts.
