MOSAIC.WAV is a Japanese moe-pop Gamewave band from Akihabara, widely known for doing theme songs to eroge, they eventually began to produce their own original work in 2004. Their name is a reference to the use of mosaics to censor the genitals in pornography, and WAV is a sound format. Their songs have also been used as opening songs for Sumomomo Momomo
MOSAIC.WAV is fronted by vocalist MI-KO, with keyboardist Susumu Kayamori, and guitarist IRON backing her up.
They dubbed their own music as Akiba-Pop, which was really a variant of gamewave, only covered by numerous Akihabara cultural references, this including fantasy anime and video game themes.
MOSAIC.WAV is currently active as a band.
