Re: 5/4 songs
Lateralus by Tool has 5/4 parts in it that are quite tricky as they're heavily polyrhythmic against the other musicians in the band...it's a head trip and I'm still learning to play it right 3 months later.
The main groove throughout goes in the following order 9/8, 8/8, 7/8. Through the rest of the tune there is a mixture of 4/4, 5/4, and 12/8. It's as if Danny Carey just said "hell with it, every odd meter I can fit into a trippy rock tune, I'm going to!".
