Led Zeppelin III is probably my favourite of the three LPs anyway but I listened to the remastered one the whole way through last night, loud & have to say I was blown away by it, I genuinely didn't think that album could sound any better. Gallows Pole has always been a song that has kind of passed me by but having heard the version on the companion disc it's given the song a whole new life, Out on the tiles has even more energy, That's the way is even more beautiful & Since I've been loving you, what can I say? Every song is 10/10 for me.
My immediate reaction is that III also has the vastly superior companion disc of the one released thus far.
