Mexican duo Rodrigo Sanchez and Gabriela Quintero, known as Rodrigo y Gabriela, are masters of the guitar.
They aggressively attack the strings like their heavy metals heroes.
They still do it on their new album "Area 52," but they have help from a 13-piece Cuban orchestra.
The album was recorded in Havana.
Anchor Marco Werman talks to Sanchez about the recording.
