Simon Reynell at Another Timbre has created a listening space titled The Anonymous Zone. I'll let his description stand:
The Anonymous Zone is a new idea; a place where music can be listened to and appreciated for what it really is, not because of who made it. Improvisation and contemporary classical music are as riddled with star systems as any other form of music, and inevitably, in spite of our best intentions, our reaction to a piece of music is partly determined by our knowledge of who is playing or has composed it. So we give more time and attention to pieces by our favourite musicians, and – conversely – we’re inclined to quickly pass over music by people we either don’t know or assume we don’t much like.
