Fair enough, Rob definitely was/is responsible for the lyrics and vocal melodisen, not sure how much he composed and arranged though. Be that as may, Priest did write their best material with Halford/Tipton/Downing. However, like Yax said above, I do believe that Tipton/Downing took The wrong musical route, and Glenn also botched the production in both albums...
...which serves as a seque to production values. All three bands suffered from terrible album productions, although I think the Martin albums sound the best of the bunch overall:
- The Eternal Idol is one of my favourite sounding Sabbath-albums (as it should be, they spent a shitload of money to it). I LOVE Headless Cross and the way it sounds, but I recognize that objectively speaking it sounds dated and is horribly mixed. Tyr, again, has its problems, mainly Cozy Powell's drums drowning Iommi's guitar. Forbidden's original mix, well, thank God for the remix...
- No need to talk about The X-Factor's sonic deficiencies. It is a big part of Blaze's raw deal that 'Arry didn't hire a real producer once Birch retired. Blaze and the band deserved better. And same goes for Priest records after Painkiller and before Andy Sneap came on board. Glenn-produced albums sound horrible, Redeemer of Souls being the worst offender. I'm not particularly fond of Roy Z's work in Angel of Retribution, it's a surprisingly muddy sounding album.
