Life's too short to spend half of every rehearsal working out what the guitarist is doing AND rehearsing the music (particularly if you're being paid for it, because you're doing twice the work you should be!)[/quote]
It really depends on how the songs are written in the first place. We'll tend to start with an idea someone has brought to the table, who will play it to the group, and we'll finish the song by jamming it out and making changes as ideas come to us - the jamming is part of why we play in the first place, it's fun!
