Can someone give me the names of some current five-piece bands ?

US5 is/were 5, I've stopped being a 팬 since almost all the original member left. I don't know about their new album either, but their newst isn't THAT old. Like 2009 또는 something?

No 천사 were a group with five girls, but the last one left.
I 사랑 their songs, check them out. They released their last album in 2009, I think.

The last band, is Lexington Bridge, I think they're about to release an album soon. Listen to Kick Back, that song is really good. 또는 Real Man ft. Snoop Dog.
