Order In Decline is undoubtedly Sum 41's heaviest and most aggressive album in their storied career, while also being its most dynamic and raw. For each fiery, arena-rock entry (i.e. "Out For Blood" – a down-tuned skate-punk number with an insane guitar solo and "45 (A Matter Of Time)" – a groove-heavy mid-tempo rager, there is an equally powerful, vulnerable ballad that hits just as hard. Producing, engineering, and mixing the album in his home studio, frontman Deryck Whibley pain-stakingly crafted and fine-tuned each song, highlighted by his fast and full riffs, guitar solos from lead guitarist/backing vocalist Dave Brownsound, harmonious chords from guitarist Tom Thacker, and the heavy, heart-thumping rhythm section of bassist/backing vocalist Cone McCaslin and drummer Frank Zummo.
