All acts get 5 minutes. To reserve a place contact firstname.lastname@example.org giving the name and nature of your act, plus which date you would like to book a slot for.
Most acts tend to book ahead and slots are in demand. However, in the event of a cancellation it may be possible to fit some walk-in acts in on the night, but there is no guarantee of this.
Prior to booking, please be aware that Diminishing Returns is a relaxed, informal event with a flat stage and shared lighting.
