Numan was set to perform a small number of American live dates in April 2010 , including a Coachella Festival appearance in California , but had to cancel because air travel in Europe was halted by the Icelandic volcanic ash cloud . As a result , the tour was not only postponed but expanded , and his Pleasure Principle 30th Anniversary Tour 's American and Mexican dates began on 17 October 2010 , at Firestone Live in Orlando , Florida
