The music of Brazilian Marku Ribas and the 13-man Batucada Sound Machine, together with eight-piece funk band Humlai, will be spicing things up during the five-day festival, with both acts promising distinctly Latino performances which blend several musical genres with tantalising flavours from around the world.
Queenstown JazzFest Trust chairman Luke Baldock said one of the strengths of the annual festival was the diverse range of musical styles which came under the "umbrella" of jazz.
"This year, we're excited to present two related but distinctly unique concerts that explore different elements of Latin jazz.
"Both performances by Marku and Batucada combine African and Brazilian rhythms and music styles that break the boundaries from the traditional style of jazz into classical harmonies, contemporary beats and soulful melodies."
On October 23, Ribas will make his festival debut in front of an intimate audience at The Millhouse, at Millbrook.
The celebrated singer, songwriter and soul master has been described as "one of the true architects of Brazilian music", with his unique style fusing Brazilian rhythms with Caribbean and jazz elements.
The following night, the Batucada Sound Machine will be back by popular demand, playing at the ASB Jazz Club in the Queenstown Memorial Hall, joined for one night only by funk band Humlai.
Famous for its sheer energy and explosive percussion, Batucada embraces Pacific soul, reggae, funk, dance and hip-hop.
"If there's one chance to cut loose on the dance floor and enjoy a musical extravaganza at the festival, then this is it," Mr Baldock said.
Advance bookings were strongly recommended, with limited tickets available for each act.
Full details of all ticketed concerts and free gigs are listed in the ASB Queenstown JazzFest programme, which is available at ASB branches in Queenstown and Remarkables Park.
