The name "Perrosky" came from the childhood nickname of Alejandro, who was originally a solo performer before forming a duo with brother Álvaro.
[1] In 2001, initially with a small repertoire of songs, Alejandro recorded his first acoustic low fidelity cassette called Añejo ("aged") and made his live debut in a bar in the neighborhood of Ñuñoa, Santiago.
After this gig, Alejandro recruited his brother Álvaro to join him on drums, and the Perrosky style changed to become more electric.
[2] Although still playing in their parallel project Guiso, the Perrosky duo also began performing gigs in Santiago and other cities in Chile.
Perrosky will form part of the line-up for the third edition of Lollapalooza Chile,[4] taking place in Santiago in April 2013.
