U2.com subscribers should be getting an email today with news that U22 will be shipped by the end of May to everyone who's a current member for 2012. U22 is, of course, the latest fan club-only release -- a two-CD collection of 22 live tracks from various shows on the U2 360 tour.
Current U2.com members should also find a bonus live track, "Unknown Caller," available for download now on the Account Info page at U2.com. This is a bonus track that's not included on U22. The email also says that eight more tracks will be available for current members to download on May 30th.
