Hailing from the West African nation of Benin, this 10-piece brass and percussion band was founded in 1994 (it was originally an octet) and has gone on to achieve international acclaim for its vibrant, dynamic shows. Making its Boston debut, the band will perform songs from its albums, ''Whendo" and ''Togbe." Oct. 23, Somerville Theatre, 4 p.m.
