Sandro Perri is a musician and producer from Toronto, Canada. His music has been called post-rock, electronic, experimental, ambient, folk among others.

Between 1999 and 2002, Perri self-released a series of 12" records on his own Audi Sensa label. Most notably, he adopted the moniker Polmo Polpo for some of his electronic compositions. Polmo Polpo is characterized by distorted drones, subtle rhythms, and ambient textures.The Science of Breath, featuring tracks culled from these records, was released in 2002 by Alien 8 Recordings; his official debut came in 2003 on Constellation Records, entitled Like Hearts Swelling. "Polmo Polpo" loosely translates as "octopus lung" in Italian.

He began touring under his own name, singing and playing more folk-tinged songs, initially acoustic reworkings of his Polmo Polpo recordings. Four songs were self-released on the Friends Help Friends EP in 2005, re-released a year later (with an additional song) on Constellation as Plays Polmo Polpo. In 2007, his debut full-length as Sandro Perri was released, also by Constellation, entitled Tiny Mirrors.

Perri is a frequent collaborator, having played with the Great Lake Swimmers, Detective Kalita, Barzin, and others. His other projects include Dot Wiggin with the late Todd Fox, Glissandro 70 with Craig Dunsmuir, Double Suicide with Ryan Driver, and Continuous Dick with Adam Marshall and Andrew Wedman.

In 2011, Perri, Christine Fellows and John K. Samson participated in the National Parks Project, working with filmmaker Daniel Cockburn to produce and score a short film about Ontario's Bruce Peninsula National Park.
