I'm really enjoying everything I've heard from Temples. Sadly I missed them a few months ago. And I'll likely miss them again next month because I don't know if I'm up for a "Morgan's Pier" event...
As for why you should check them out? They sound a bit like T-Rex? That should be enough for anyone.
Truth be told my reggae knowledge is pretty much limited to Bob Marley (and his offspring) and Peter Tosh. I should really dig deeper, but I don't even know where to begin.
