On their first full-length album, Kobe's Mamadrive prove pretty good at capturing the energy and power of their live shows. Masako Shibuya's strong voice leads the songs and her distorted bass lines work with Maika Sasakawa's guitar riffs to weave counter-melodies around the vocal ones. The noisy and more complex indie-rock elements in their music show influence from 1990s alternative-rock acts such as Number Girl, while the emotional vocal style — and commercial accessibility — comes more from that decade's J-pop and pop-punk scenes.
The first two songs on "Mousou Tengoku" ("Heaven Delusion") immediately bring in the band's urgent rock sound, but the album really gets interesting from the third track, "Welcome to Night," a catchy — and even funky — faster number. The track starts with a drum build-up, then the bass line brings the funk in. The first hook develops with repetition of the word "hello." Mamadrive then take a power-pop-style sudden music pause before bringing in a big chorus, a technique they also use on the first two songs, but on "Welcome to Night" it has a much more dramatic impact with Shibuya screaming the titular phrase.
The fourth track (another highlight), "Hebi no Onna" ("Snake Woman") continues the power-pop idioms with controlled guitar effects, before fifth track "Kurai Yoru" ("Dark Night") suddenly brings the pace down for a welcome break.
