Straight from the good folks over at Club Congress, it appears that Os Mutantes, featured on our cover last week, is having transportation issues and can't make it to Tucson in time for the show.

But, like Bradley Cooper, Club Congress is finding that silver lining, and offering a show tonight, featuring Capsula and local band Chicha Dust for the low, low price of absolutely free.

Even better? According to Club Congress, Os Mutantes is in the process of lining up a return date — possibly as soon as May 12. If you're too upset to consider hanging on to your tickets, Congress is offering to refund your ticket.

From Club Congress:

UGH! One of the most anticipated shows we've had in a loooong time has been delayed by an engine fire. Os Mutantes are stuck in Texas!!! They will not be able to get here in time! Terrible news with a small silver lining. They have already promised a make up date on May 12 OR when they return for the 2nd leg of their North American tour. Your ticket will be honored for that should you wish to hold on to it. Otherwise we will refund at point of purchase. MORE SILVER LINING. Capsula, an absolutely awesome psycedelic band from Buenos Aires (hand picked by Os Mutantes) are still going to play, as well as Tucson's best new Psychedelico super group, Chicha Dust ...and because we are all sad we are making the show FREE! Chicha Dust says "we would like a nice long dance party set"... now that's making the best of a bad situation.
