To celebrate the 21st anniversary of their debut release, Blur's last (to date) album Think Tank has now been expanded across two discs, cut on heavyweight 180 gram, audiophile vinyl and housed in a replica of the original sleeve artwork.

Over six lauded records, the most notable feature of Blur's sound is that they really don't have a sound. In a musical world where artists are all too often pigeonholed, Blur remains the ultimate indescribable, unpredictable band. With the possible exception of the first two, no Blur album has really borne the mark of its predecessor, and their seventh offering 'Think Tank' is no exception.

Practically every track goes off in its own engaging direction, starting with the darkly hypnotic and mystical "Ambulance" which abruptly closes on a distorted synth riff and crashing into the sweetest song on the album, the melodically simple and reflective "Out Of Time." The one constant on a Blur record is the knowledge that there will be at least a couple of perfecly-etched pop songs and on this go-around, they're even clearly, cheekily marked "Good Song" and "Sweet Song." Along the way, there's also the spacey danceable screaming of "Crazy Beat," the old-school punk of "We've Got A File On You," the world-beat/Manchester recall of "On The Way To The Club," and the ambient chant of "Caravan."
