YEah! I know that in flames are co-headlining with killswitch engage but on the ticket I bough it was in flames in big letters and under that there was killswitch engage and as I lay dying. So this is good!
well for the Los Angeles show, if you go to the venue website it's listed as In Flames. But then if you go to the venue website for the San Diego show, which is the day after, it's listed as Killswitch. So that pretty much hints towards a rotation in the headlining spot.
