Here's a teaser for you: how loud can a band get whilst still remaining deeply melodic? I guess it's really a rhetorical question, as I'm sure it differs from person to person (Megadeath for example are described as the world's loudest band, and they've never floated for me). One band however that can be both loud and incredibly hook-laden are Danish six piece Kandy Kolored Tangerine.
On their song "You Are, Boy", the band mix the occasional falsetto and structure of The Temper Trap with the relentless wall of noise style of Sonic Youth for an epic, anthemic track that pushes the red to it's ultimate limit. After many years of searching, I might have finally found the exception to the rule 'If you can't play it well, play it loud.'
