With CW stuff the most productive way to write starts with Ross and I having a jam at my house. We usually start with playing all the ideas we've had for guitar/bass parts then jam with something we reckon could go somewhere. Often we'll just jam out a part until it's tight, then we'll have a pretty good idea of where we're going. Often one of us will 'hear' a rhythm that could go well from there, or that one of the parts previously played could work. We try not to get too hung up on concrete rhythms until we get to full band practice. In the past we've demoed the tracks at the living room stage and fired them to Dallas to get an idea of rough rhythms/flow. Take the idea to full band practice and get each part reasonably tight and edit any parts that aren't quite working/that could be better (usually consisting of a lot of guitar/drum onomatopoeia, waving, pointing, nodding, descriptive jargon e.g. attack, drive, pummel - then and eventually "YEAH"s). Go through the last cycles of parts and concentrate on getting the changes tight, then finally we go from the top and forget everything we just did. Ideally demo the tune again with drums and send to all members to make sure they don't forget, which we are all pretty good at. I usually use the demos to try and come up with vocals using overdubs etc. Done!
