So a about six months ago I noticed one of these knocking around work, bought ages ago but never even taken out of the box. It's a simple audio interface you can plug your iPhone straight into for kind-of-useful two track recording. I used it to record a duplicate of the main outs on the desk... either way it gives you heaps of control over the gain structure of what you might want to record to two track on your phone.
Stacey from super cool Adelaide band Terrible Truths filmed and synced this little clip of NO ZU.
