Define "Big".
For bands larger than bar scene:
Live in 97, they had Fun Loving Criminals open for them.
Brooks and Dunn later that year. Joe Diffy opened.
Garth Brooks the next year. Sold out 3 shows in 40 minutes. A friend paid a street guy in Whoppers to stand in line with him. Curt bought his 6 tickets, street guy bought his 6 and then we scalped the 2nd six. Everyone got to see him for free and pocketed 20 bucks.
Last larger act I saw was Flogging Molly both Frank Turner and The Architects opened for them. Best show out of all of them.
