Now that, after 5 years of waiting, the Durarara!! animation has been blessed with a continuation and therefore the conclusion of the complete story, naturally Makoto Yoshimori, the composer of the first Durarara!! score, has done himself the honour and contributed more atmospheric tunes for the second and final season.
What struck me as most impressive about the evolution of the score is how Yoshimori has managed to maintain the atmosphere from the very first track in 2010 to the very last in 2015. And yet it has undergone a lot of change befitting the characters. In the first season of Durarara!! we were confronted with Ikebukuro and its inhabitants getting entangled in all kinds of unbelievable plots. It’s an introduction – a prelude to later, even crazier events – and therefore the show feels a lot more high-spirited. The music adds a lot to that. It’s lively and nonchalant and psychedelically crazy. In comparison the soundtrack of the second season feels a lot darker in many aspects. The three parts of the Durarara!! x2 anime are the climax of the series all the way down to the conclusion: those are the moments when all the truly shocking and menacing twists and turns happen, when the characters we got to know grow up or crumble and become something else entirely. Thus, on the second and third score we find considerably fewer tracks with an easy-going atmosphere to it and it only makes sense. The fast-paced tracks have a different feeling to them and though they might still be upbeat, they lack the touch of ease and nonchalance that we experienced on the first season’s OST. Only with the fitting music the atmosphere can truly be brought across to the viewers. Yoshimori has managed to create a perfect symbiosis between music and anime but despite that, his style still remains distinctive to the very last note. This is why the Durarara!! score is one of my favourite works out there: in my opinion it perfectly captured the mood that Ryougo Narita described in his novels, it is what supports the animation the most (right after the voice acting) and simply by listening to the soundtracks you can experience the adventurous, bizarre story of Durarara!!.
