The xx are set to play a run of 25 shows for just 40 people at a time.

The gigs will take place at Park Avenue Armory's Wade Thompson Drill Hall in Manhattan, New York from March 19-29, 2014. Two shows will take place every night, with three on the weekend dates, reports The Line Of Best Fit.

A statement about the shows says the gigs will be "uniquely voyeuristic and deeply personal". It reads: "Defying perceptions of a traditional concert, The xx creates a site-specific environment to delve into uncharted levels of depth in their sound where dark and light collide as the memory of the outside world falls away. This uniquely voyeuristic and deeply personal setting is the perfect oasis for the band to perform, while in the process redefining their music and their relationship to the audience that surrounds them."

The band last month issued a statement saying they "unconditionally" support the right to equal marriage after a Croatian anti-gay marriage pressure group used their track 'Intro' in an online advert without permission. The organisation, U ime obitelji, which translates in English as The Name Of The Family, garnered enough signatures to force a referendum on an equal marriage ban in Croatia.

"It has come to our attention that our music has been used without our permission in a promotional advert by the Croatian organisation "U ime obitelji"," the statement posted on the band's Facebook page read. "We wish to state that we didn't, and would never, approve the use of our music by this organisation. To be clear, we unconditionally support the equal right to marriage regardless of sexuality." The advert has now been taken down.

The xx recently released special vinyl boxsets of their two albums. Every track on the band's 2009 'xx' debut and 2012's 'Coexist' album has been pressed onto seven-inch vinyl and packaged into two limited edition boxsets with individual artwork for each record. Each set costs £55 and is limited to 1,000 copies.
