If you’re talking about modern progressive rock and don’t bring up Haken, you’re doing it wrong. Since the south English sextet started jamming together in 2004, they’ve been one of their genre’s most loyal yet, simultaneously, adventurous forces. Every album they’ve released is distinct from all the rest, but they’re all tied together by their incalculable time signatures, fearless songwriting and majestic vocals – and, of course, their critical acclaim.
