From 2013 to 2025, Azcano was a member of the Eos Guitar Quartet, praised by Leo Brouwer as “one of the best guitar quartets in the world.” During this period, the quartet performed music dedicated to them by legends like John McLaughlin, Paco de Lucía, and Ralph Towner. Since 2025, Azcano has focused on his own musical and academic projects, including a doctoral dissertation on improvisation for classical guitar at the Freiburg University of Music in Germany.

The Eos Guitar Quartet has an international reputation as one of the most distinguished ensembles of its kind and continually amazes both the public and the press at its concerts and records. The Quartet is regularly invited to play at the most important international guitar festivals and in the most renowned concert halls.
