I'm sorry to say that a friend gave a copy of the CD, to replace a stolen one. There's no 'tron on it as far as I can hear, and it's one of my favourite albums of all time. I'm pretty sure that it was released in 1991, though, because I have a vinyl copy of Reflecter, and I know that's their second LP, and it was released in 1992.
