This thread is for all the alternate mixes, demos, or re-recordings that people may find better than the regular album tracks. I would like to exclude cover songs and MOST live versions as those would be easy picks. I do count live versions that significantly change up the sound or format of the songs. Like making it acoustic, adding an orchestra, or greatly adding onto the original length of the song. Here are a couple of mine.
Candlemass - Witches (The Tony Martin Demo)
https://www.youtube.com/watch?v=1RihZnl26OY I had no idea this existed or that Tony Martin was ever close to joining candlemass until recently but I really love this version of the song. I like the alternate lyrics better than the later version and Martin's vocal melodys I find more memorable and catchy than the Marcolin's take on it.
W.A.S.P - Hallowed Ground (Acoustic)
https://www.youtube.com/watch?v=vgGmnnRwUTQ This version really brings out the emotional side of Blackie's vocal range which I think is where he really shines.
Ozzy Osbourne - Mama I'm Coming Home (Demo)
https://www.youtube.com/watch?v=kLVohjRgNs0 I honestly could've filled this thread full of Ozzy demos. Every one of them that was released on the Prince of Darkness boxset I like more in some way than the album versions. This one in particular I think is better in every way than the version that ended up on No More Tears.
Sanctuary - Die For My Sins (demo)
https://www.youtube.com/watch?v=MIIKrFvHLCA Really makes me want to hear what Chris "Zeuss" Harris could do with the actual Refuge Denied masters as this demo is far better mixed IMO than the album cut.
