depends on where the stage is. The good thing is there are not really bad seats there. Just some are a little better than others. We where in the same area for Elton John last year. Those are good tickets for an "in the round" concert which means all open in the center.. If the stage is left youll be behind the band which wasnt bad for elton because when he sat at the piano he was looking at us.
We have been to many concerts there and usually the block off 7-10 if it is a back drop stage. Section 3 is AWESOME seats...congrats. We are seeing Elton John again on the 8th right after you and we are in row 32L which is good seats also.
I used to be a stage hand at the Coliseum, so I can help here. Best seats are are sections 15L first row, and 3L first row. Sections 4-14 are typically blocked off for a big show with a big stage presence and 6-12 blocked of for a small stage show. Country shows are sometimes in-the-round which makes sections 1 and 17 preferred seating.
Your seats are very good for a standard layout, and not bad for in-the-round. Your initially posted seats wouldn't have been too hot, somewhere in the vicinity of section 32A, but out on the floor.
