Last night me and some of my friends had a massive jam for a few hours. People were jumping in and out and there wasn't always this much going on but at its peak there was two drummers on two kits, two basses (my 5r fretted warwick and my friend with a fretless 4 string p bass), 3 guitars. I had a really good time! I liked having my time to sit back and also to jump up for a solo/lead section. I also really liked the way there would get to be a few 'mini jams' going on every now an then with maybe a bit of call and response between basses or guitar and a drummer. The kind of stuff we were playing was a bit mars volta - esque, obviously not of that calibour! But that sort of feel. I did have one problem though, for a while there was just me on bass, the two drummers (who were tight) and three guitarists. Two of them were soloing, excessively but tastefully and giving each other room. But the other guitar was playing quite quietly but still loud enough to be noticed and was not really playing anything that fitted with the rest of what was going on. I found myself feeling lost because I wanted to lay down something solid under the solos but I was finding it really hard to play tight with the other guitar taking the rhythm role. The stuff he was playing was quite cordal but in a weird time and was changing in odd places and I really struggled trying to keep the groove going. What would you guys have done in this situation?
