You may think Tribes is surely an American band circa the late 80's in the Northeast or early 90's in the Northwest but you are sorely mistaken on this one.
Actually, they are a band that formed in 2009 in London that got their start passing their demo out to friends and playing every possible gig in the London underground scene possible till the buzz really started to grow. Now, they are opening for everyone's new favorite band (so it seems), Mona.
There isn't too much music going around YET but you can listen to some of the demos at the band's Soundcloud and MySpace page.
For now, here is a live video of their track Whenever live at XOYO in London
