Whenever I see D4E (which is a few times a year at a lindy exchange - in Sydney, in Perth, in Melbourne) we plug our earbuds into each other's mobile music devices and play each other music.
This is where I learn about music that isn't jazz and wasn't released in 1992 on Shock Records.
I only play music - he makes it.
