SummerStage is hipster heaven on this Sunday, when we feature two groove-heavy groups and an avant-garde marching band.

SummerStage is delighted to welcome back Brazilian Girls, the ultra-hip and wonderfully breezy groove band that first appeared at SummerStage two summers ago. For those who don’t know, only one of the Brazilian Girls is a girl (front-woman Sabina Sciubba) and none of them are actually from Brazil. But the name perfectly fits the globe-trotting vibe of their music, a playful mix of electronica, bossa nova, vintage French pop and rock. Their sophomore set Talk To La Bomb was released last year, and Spin magazine called it “multicultural, cosmopolitan, intellectual dance music: Ibiza meets punk, dub goes tango, trance gets smart.”

Originally formed as a keyboards, double-bass and percussion trio in the late ‘90s, Melbourne, Australia’s Cat Empire quickly expanded to include a trumpet player, a drummer and a full-time DJ. Such unusual instrumentation is only one indicator of Cat Empire’s unique style. The band has filled three albums and over 500 live performances with an (iconoclastic) mix of hip-hop, reggae, alt-rock, Afro-Cuban jazz and pure experimentation. The latest album, Cities, was praised by Australia’s The Age: “the Empire's humorous capacity to make light of genre borders is a great deal of their charm, and the jam-based construction of Cities ensures an even more lunatic eclecticism.”

HIMALAYAS doesn’t seem like a project for the age of downloads and digital music. A marching band that prefers to play on the street and have its audience participate in the show, it’s almost the antithesis of today’s music: it’s spontaneous, organic and ephemeral. This is exactly why drummer Kenny Willeson and saxophonist Jonathon Haffner started the band in 2000. With an ever-changing cast of characters and a penchant for mixing genres--Cajun tunes with Downtown atonality; fusion jazz and disco jams—HIMALAYAS is a marching band experience like no other.
