who have a detail about soad new album??

I'm sorry to say this dude, but system of a down broke up a year ago. They are "on hiatus for a few years", but it is doubtful they will be back together for a while.

The last I heard, they had gone on an indefinite hiatus, so that each of the band members could work on their side projects. Of course, I also haven't heard anything about what those side projects are doing, so perhaps this "hiatus" was just an excuse for a well-deserved break. They did put out two albums back to back a year or so ago!

They have shown no indication of getting back together to work on a new album. It will probably happen at some point though, so hold your horses. For now, just enjoy Serj's solo stuff. Speaking of which, what was Serj's first single called? Anybody know?
