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. 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.
