Hey I recommend you all try to find the chords by yourself lads ! I'm not teasing you at all. Antimatter and Anathema songs aren't very difficult if you wanna play them acoustically.
You can make easy adaptations, there aren't many maaaaaaaaaany chords used in the songs.
And training your ears to find chords you don't know yet is good for self-musical improvement
But I know we're sometimes too lazy to do it and tabs can be useful so ... if I can help ... who wants which song ??? i know some, just ask.
