Aguirre is the second disc for the ensemble called Los Otros (The Others), which consists of the partnership of German viol player Hille Perl and American lutenist Lee Santana, along with a a second string player, the appropriately named Steve Player, and Spanish percussionist Pedro Estevan.

The group investigates the fascinating repertory of Baroque-era music from Mexico, a focus that seems obscure until one hears how features of this music have trickled down to the present day.

The inspiration behind Aguirre, for example, began to take shape when Los Otros met a group of Mexican folk musicians in Veracruz state and noticed similarities between the Mexican musicians' instruments and their own Baroque specimens.

The ringing xarana (more often spelled jarana), a small guitar that gives some genres of Mexican folk music their characteristic sound, is heard frequently on this disc and blends right in with a viol and Baroque guitars.

Veracruz is the most Caribbean of Mexico's major regions musically, and the rhythms of the modern son jarocho, the most famous example of which is the song "La Bamba," are heard in the music Los Otros play on this disc.
