P86 took me a loooong time to get into (hated Schwab's vocal style for a while) but to this day they're one of my all-time favorite bands. So much creativity going on there, especially on And The Rest Will Follow.
Without them I probably wouldn't listen to as much diverse heavy music as I do.
His vocals on later albums where he does more singing can get grating for sure. Drawing Black Lines and Songs to Burn Bridges By will always have a place in my heart though
