gonna book a day in a practice room, and start getting our bassist up. ive known him a long time and we both think the same way on stuff. im also moving house soon so im gonna have a good clear out and a change of environment. that might help too.
last time i had something done, i spent all day walking round going over riffs in my head, and then eventually i just wrote the extra parts in my head, went home and jammed it. that still needs work, but at least its pretty much 1 down.
