Animelo Summer Live is the biggest annual anime songs concert in Japan managed by Animelo Mix. Animelo Summer Live has been held every summer since 2005. Animelo performers are singers and voice actors that specialize in singing anime or game theme songs. The performers are not necessarily under the same record label. Animelo's performers are often called Anisama Friends, and are represented by famous anisong singer and Animelo producer Masami Okui. The highlights of Animelo concerts are the collaboration between the performers. Animelo has a different theme song for each year, which is sung by all performers in the end of the concert.
