Out of their first 3 albums, it was Fly By Night that I didn't much care for. There were a couple of tracks I liked on it. I love the first album because it's so heavy and raw. It's amazing what a difference another drummer makes. I think John Rutsey was diagnosed with something or other, MS I think so don't quote me on that lol, and that's why he left. Again, I might be getting him confused with John Hinch, the drummer on Judas Priest's 1974 debut.
