If the debut laid down the premise that Diagonal were to be the retro progressive rock band to be reckoned with, then The Second Mechanism fulfills that conclusion. Perhaps more studied than their first opus, with even more twists and turns to keep the modern short-attention-spanned listener completely enthralled - ironic given Diagonal's 1971 disposition. But such was the state of that era - and ours. Diagonal are a band that have gone from great to greater, and I can only imagine what they will come up with next. Let's hope the group continues to explore these paths that were not as tread upon as many people might initially presume. Diagonal are walking the little known side trails from the main highway. And there are many aural treasures to be found.
