Information:
The name of this hip-hop/raggae group comes from the English word "Spontaneous". Spontania has become well known for their releases that collaborate with other artists (JUJU, Ito Yuna, etc.).

While both members are Japanese born, they both went to study abroad in the US while in high school. Massattack did some DJ work in New York before even debuting in Japan at all. In fact the group themselves met in New York in 1996, and formed the group "Hi-Timez". In 2004 they would debut under that name. However in 2007 they would meet Micro
(then of Def Tech, now a solo artist). Under his label they would change the group name to Spontania.
