Promotional materials for "On-Gaku: Our Sound" celebrate the feature's very existence, with director Kenji Iwaisawa putting in a heroic effort to simply complete the picture, which was seven years in the making. It's also completely animated by hand, with use of the rotoscoping process to bring to life a rather small story of adolescent awakening via the power of music. The material takes its inspiration from a manga written by Hiroyuki Ohashi, giving Iwaisawa a storytelling direction to follow while the production cooks up its own wonderland of attitudes, musicianship, friendship, and personal expression, sold with an exquisite dryness that pulls humor out of the strangest of places. "On-Gaku: Our Sound" loves its stillness (probably for financial reasons), but it's a marvelous exploration of an askew liberation. It's as small in scale as an animated film gets, but it delivers such a wonderful understanding of character, detailed through inventive and unusual artistry. Read the rest at Blu-ray.com
