Sandro Perri is a musician and producer from Toronto, Ontario, Canada. His music has been called post-rock, electronic, experimental, ambient, folk among others. He has been producing, mixing and mastering records for other artists since 2003.
Between 1999 and 2002, Perri self-released a series of 12" records on his own Audi Sensa label. He adopted the moniker Polmo Polpo (loosely translates as "octopus lung" in Italian) for some of his electronic compositions; Polmo Polpo music 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; the official Polmo Polpo debut album, entitled Like Hearts Swelling, was released in 2003 on Constellation Records.
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. Several musicians contributed to the overall direction of the record, including The silt (Ryan Driver, Doug Tielli, Marcus Quin), Blake Howard and Eric Chenaux. That year Polmo Polpo performed at the Brampton Indie Arts Festival.
In 2013, songs from Impossible Spaces were remixed by Zongamin, Mickey Moonlight, Eluvium, Max Gross, Larry Gus, Le Revelateur, Imugem Orihasam, Slow Hands and Tom Croose for 12"s on DFA Records, Constellation and Phonica.
Perri played lap steel guitar with Barzin  in 2001 and Great Lake Swimmers from 2002-2006. He is also a member of The Michael Parks. Collaborative 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.
In 2016 he released the electronica album Off World, with a follow-up album simply entitled 2 released in 2017.
