You should always buy concert and event tickets in advance. Often times you get a better deal if you buy tickets in advance because of early bird specials. So you save money by getting tickets in advance. Venues in Midland and Odessa Texas are very limited on capacity so buying tickets in advance ensures that you will get to go. I have seen dozens of shows sell out due to capacity and then people freak out to try to get tickets. Another reason you should always buy in advance is that there is so much money that goes into bringing artists and entertainers to this area. Venues, promoters, and businesses spend thousands of dollars to bring artists to the area, and without advance ticket sales there is a huge risk that the show could get canceled. Continue to support local events and concerts by buying tickets in advance!
