'Attractive Museum' is an album that, at first glance, may feel unfocused and lacking cohesion. However, listening through the songs over its runtime of over an hour, you can catch a glimpse of distinctive tracks across various genres: from songs showing the signature Shibuya-kei sensibility of OSTER Project (POMPADOUR), relaxed bossa nova (魔法使いのショコラティエ), sensually charming jazz (on the rocks), intense Japanese-style rock (狐ノ嫁入リ), to a grand symphony themed around medieval knights (レツェルの騎士).
Although tracks of different genres and atmospheres seem scattered around, establishing the album's identity as a 'museum' conceptualizes and explains this structure. I believe she creatively built a narrative using OSTER Project's own musical traits and strengths for an album that could have easily ended up as a plain single compilation.
In particular, the final track 'Music Wizard of OZ' is a musical-concept piece spanning a full 20 minutes featuring seven Vocaloids based on The Wizard of Oz, which is extremely encouraging as music that only OSTER Project can pull off. Having already introduced her own new genre called "VOCALOID Musical" through 'Alice in Musicland' about two years prior to this song, presenting another musical track to listeners subtly reveals her intention to further pioneer this experimental attempt.
In conclusion, it is a great-quality album that clearly demonstrates OSTER Project's broad musical spectrum while successfully establishing a narrative for the album.
