Has it really been a decade since Kaoru Ishibashi — better known via his performing name Kishi Bashi — released his full-length debut, 151a, a dense, richly layered effort inspired by everyone from The Beach Boys and Steve Reich to Animal Collective and Sufjan Stevens? A classically trained violinist who studied at the Berklee College of Music, Ishibashi initially sharpened his Pop chops as a contributor to songs by the likes of Sondre Lerche, Regina Spektor and of Montreal. Kishi Bashi’s longtime label, Joyful Noise Recordings, is celebrating the 10th anniversary of 151a with an expanded reissue of the album that includes demo versions of each song. The corresponding tour — which stops by Madison Theater — will feature Ishibashi and his band running through the album in full while also sprinkling in selected tunes from the rest of his discography.
