Update: All tickets have been taken. They were gone in about 12 minutes. Organizers say extra tickets may be released later this summer. The CSO is also warning people about purchasing tickets from third-party sources:
"We've noticed individuals putting #LUMENOCITY tickets for sale online. This is a free community event, and if you have requested more tickets than you need (four was the limit), you're encouraged to invite friends and neighbors to come with you. If you requested more than four, the order could be voided and those tickets would made available again to the general public. Please understand these sellers do not have their tickets yet to sell."
The Concert and Light show known as Lumenocity is coming back to Washington Park this August, and if you want to go, you'll need a ticket. The Free tickets are available online this morning starting at eight o'clock at lumenocity2014 dot com. Each household will be limited to four tickets for one of the performances August 1,2,or 3. Organizers expect tickets will go quickly. Capacity for each performance is 12,500. For those without internet service you can go to a branch of the public library today to get tickets.
