Recorded during two magical sold out nights at Teatro ND Ateneo in Buenos Aires, this album by Pedro's group's 2002/2004 line-up (Alejandro Devries on keyboards and voice, Diego Clemente on guitar, winds and voice and Facundo Guevara on percussion), features several previously unreleased songs and new versions, the reunion of legendary trio Madre Atómica on the same stage where they played together for the last time in 1975 and brilliant contributions by very special guests.
