I'd like to avoid attempting a genre definition for the Tony Castles. If you've found this page then surely you're savvy enough to find the most current and therein most accurate representation of their music. Not too long ago they went to Germano Studios in Manhattan to record a new set of their first few songs.

Everything is being mixed at the moment, but the little I've heard is nuanced and extra crispy. When there's enough bullshit out there drowned in the safety of incomprehensible nonsense (not the nice kind), the world waits for music like this. Hopefully we wont have to wait too much longer...updates on the way.
UPDATE: New tracks on their Myspace.
