It really does depend on what your style(s) are. If you're a straight out rock band, then have a couple of songs that start with bass & drums & just extend the intro, play a short solo piece or let the drummer do a solo & add incidentals in (if you practice together, then you could have certain parts where you play along just a couple of notes).
In my old rock band, our drummer would play something completely random (usually jazz based) & we'd just jam an unusual version of a cover, usually so it wasn't known to start with & then once everyone was ready we would break into the song (quite often it was Use Me, by Bill Withers as the chords are just E & A so the band recognised it).
If you can get away with it, have a listen to some DnB. [url="http://ourhelicalmind.bandcamp.com/"]Our chap here has some good stuff that's just Drums & Bass...[/url]
