Four people can play wirelessly, and in keeping with LEGO's kiddy-friendly vibe there's a Super Easy mode (even the Expert mode isn't too tough). All the songs are playable from the off in Quickplay mode too. There are loads of unlockable extras to buy with amassed studs – costumes, instruments, furniture and staff – and they're all drenched in trademark LEGO humor so you'll want the lot.
There's nothing radically new here but it's all been done very well. Not bad for Rock Band's DS debut, eh?
