This app is perfect for anyone that wants details, broad or minute, about Pearl Jam's continuously updated live performance career. For those of us who see the band live this app also provides a great tool for your own personal concert going history. There is only one change I would want: support for tracking your bootleg collection. Currently there are two tabs: Pearl Jam Stats and My Stats. The latter is identical in function to the former only filtered to which shows you attended. If you could simultaneously filter shows that you have bootleg copies of, this would possibly be the best example of an app for a fan of any band.
