Their first since being on the Warner's payroll, Puzzle is an album that is likely to divide opinions. Die-hard fans may think that the band have sold out by signing to a major label and adding an extra layer of studio polish to their sound; others will simply hear a very good rock record made by a very talented band.

Past Biffy offerings have been collections of twisting, prog-tinged anthems; epic musical journeys in bite-sized form.

Puzzle certainly seems as though it will continue this tradition as opener Living Is a Problem Because Everything Dies arrives in suitably overblown fashion with orchestral stabs and choral vocals before taking a turn into FM radio territory and finally reintroducing the strings (courtesy of the Seattle Symphony Orchestra) for a grandiose ending.

It's almost exhausting to listen to but is undeniably brilliant.

Following the over the top introduction, a strange thing happens - Biffy go pop. Saturday Superhouse was a bona fide top 20 hit and songs like A Whole Child Ago and Who's got a Match? see the band delivering the kind of short, punchy, hook-laden songs that have been few and far between in their career so far.

Never a band lacking in ambition, clearly Biffy Clyro have set the controls for the heart of the charts.

There are still flashes of the Biffy of old. The stop-start riffing of Get F****d Stud and The Conversation Is… in particular would not have sounded too out of place on 2004's Infinity Land but Puzzle's strength lies in the more direct, accessible cuts.

The album reaches its peak with Folding Stars, Simon Neil's lament for his late mother Eleanor which manages to be heartfelt and moving without ever straying too close to slushy balladry.

All in all, Neil and brothers Ben and James Johnston have managed to make strides into the mainstream with Puzzle. Fans of Foo Fighters and Queens Of the Stone Age should easily be able to get on board with Biffy and if the hardcore followers can look beyond the shiny production and upsurge in popularity they will find a lot to enjoy here.
