It looks like Chris Cornell and Duff McKagan aren't the only famous friends who will be joining Mad Season when the band gets back together for a one-off performance on Jan. 30.
Pearl Jam guitarist Mike McCready has announced that Screaming Trees front man Mark Lanegan will serve as a vocalist for the newly-reformed Mad Season, Bloody Disgusting reports. It is not known if he will be the band's only singer, or merely contribute on a few songs.
