Leonard Cohen - You Want It Darker (not a classic album in itself, but it was the last in a series of really strong albums recorded after a lengthy hiatus after decades of subpar material)
Ian Curtis - Closer
Bon Scott - Highway to Hell (do these count?)
Gram Parsons - Grievous Angel
Jimi Hendrix - Electric Ladyland
Řystein Aarseth and maybe Varg Vikernes - De Mysteriis Dom Sathanas (maybe shouldn't count)
Kurt Cobain - In Utero
These frontmen ones might be a bit far afield.
