Can only see them once because Ticketmaster adds another $36 in fees, but this only shows up after you've managed to get through the queue and if you think about it too long, you'll lose your spot.
Ah shit, sorry, they accidentally sold your tickets on their scalper site for $1244 (plus fees and taxes), but don't worry, you'll get a refund.
They play some, still. But not a lot. At least not in the US. They're playing in Vegas in April this year and that's it. I remember back the first time I saw them. Think I paid like $20. Good times back then.
At current there is not much shot of an actual tour (Serj doesn't want to) and there's just been those two songs in 2020 since 2005. There's always hopes or hints or speculation of a new album, but really it just doesn't seem like it's going to happen.
