With thanks to Yesfans member Paul Vaughan for the heads-up, today this information was released regarding ARW taking part in the Ravinia Festival in Highland Park, IL on September 7th. Ravinia is more like a concert series than what is considered to be a traditional festival, so I would assume the performance will be much like normal, with a roughly 1 hour and 45-minute setlist and no other band(s) on the bill.
