Beginning in summer 2003 as a one-off commission for audio weblog Muted Tones (from which opening track “Something is excerpted and re-edited), Glissandro 70 is the result of two years of intermittent collaboration between Toronto’s Sandro Perri (Polmo Polpo, Continuous Dick) and Craig Dunsmuir (Guitarkestra). Produced by Perri with Dunsmuir and written by Dunsmuir with Perri, this five-song full-length circles at the intersection of pop song and extended dub, cribbed lyric and wordless chant, odd meter and straight beat. Playful nods to dance music’s misfit past both direct (the use of chanted quotes from Model 500 and Talking Heads) and secondhand (“Analogue Shantytown”’s debt to Arthur Russell and Walter Gibbons) are kept in check by Dunsmuir and Perri’s respective rhythmic and timbral acuities, ensuring that this is no mere exercise in exorcism.
