The 2014 iTunes Festival took a rare classical-guitar turn recently, when Montenegrin phenom Milos Karadaglic performed as part of a “classical” installment of the typically pop-heavy month-long music showcase at the Roundhouse art center in London.

Milos, as he is known professionally, performed works by Manuel de Falla, Consuelo Velázquez, and was joined by accordionist Ksenija Sidorova for a passionate take on Astor Piazzolla’s Libertango.

Other highlights of the September 28 show included a moody Milos version of Antonio Carlos Jobim’s “The Girl from Ipanema,” and the slow movement from Joaquin Rodrigo’s Concierto de Aranjuez.

The iTunes Festival has featured a classical segment since 2011, when Lang Lang performed with 2Cellos.

Milos follows up his iTunes concert on October 9 at London’s Royal Festival Hall as part of A Night Under the Stars, where he’ll perform Rodrigo’s Concierto de Aranjuez as part of a benefit for The Passage, a charity dedicated to curbing homelessness.
