Another 5/4 meter. Stays constant though. You can add dynamics at your own discretion. Again it works at a variety of tempos.
With its 12 bar structure I wonder if this would make for an interesting blues solo in 5/4. Put a standard progression under it. Pitched instruments like the guitar could just add the notes of their choosing. Drummers could orchestrate it however they feel.
