Presale ticketing has begun for the Chicago shows, per the link in my earlier thread.
For the May 22 Sunday show, there are 2 presale categories, JAM and 93XRT, but both presales seem to target the same $40 general admission tickets.
The password BLESSED works for the JAM presale.
BLESSED does not work for the 93XRT presale.
For the May 21 Saturday show, there is only the JAM presale for $40 general admission, and BLESSED works. For Saturday only, there is also an external reference to http://www.chicagohomeless.org where the Chicago Coalition for the Homeless is selling $85 VIP reserved seats.
