Unfortunately, Trey solo, TAB and/or other side projects ticket barcodes are not redeemable like Phish tickets. If your barcode is redeemable for an in-app stream or download it will be specifically noted at the time of purchase and/or on your ticket. 

You can listen to the shows with a LivePhish+ subscription. You can try a 7-day free trial at https://try.livephish.com/plus/
