Single Mothers shouldn’t exist and neither should their debut album, Negative Qualities. Led by mercurial troubadour Drew Thomson, the band was shakily hatched in London, Ontario where it ran through a dozen members before finally recording its debut album last year. At 10 songs, Negative Qualities serves as the perfect introduction to one of Canada’s most ferocious young bands – an explosive mix of raw energy, high-end punk and intellectual rendering of small town frustration.
