I don't have much in the way of details, so I'll share what little I know. Ace McNeeley is in the hospital, and in a tweet he is reportedly "in the fight of his life". Those in the music scene have most likely met Mr. McNeeley at some point. He has performed in multiple bands, including The Double Downs, Little Big Horn, and Grant Jones & The Pistol Grip Lassos. In addition, he teaches at Zounds Sounds and does sound at City Tavern.
Ace, our thoughts and prayers are with you. I'll update as I know more.
