I know this crops up every so often in sub-threads but maybe we should have a proper stab at giving it its own thread. Acts who could actually be far bigger than they are, given half a chance / a big advert / a "good will hunting" moment...

My top 3:
The Veils (new tracks http://drownedinsound.com/news/4141695 )
dEUS (should really be as celebrated as Sonic Youth)
The Stills (could not be more excited for their next album)
