Yeah, Layne Staley. One of the greatest rock'n'roll vocalists... Nah, one of the best vocalists ever overally. If you like his voice you should listen to some Alice in Chains, this song is from period where his vocals were "bad" for his standards.
yeah... it wasnt professionally recorded at all. just some free android app then loaded it to a song sharing site (clyp.it).
if youre interested, heres a youtube link i just made: youtu.be/0OcONJGcEdc
