> Where did Auditeer musicians cut their teeth in their early bands,
practice-wise?

Definitely garages. Moved up to a spare room in a rental house with my first really successful band (www.auntiegrizelda.com/Sea7States.htm).
Felt like I'd hit the lottery when I got a house with a basement and a spare bedroom (for the control room).

Now we rehearse in a music store. Don't even have to bring an amp or an instrument - just pick one from the wall. (www.glaze.tv)
