With 2007’s deceptively layered breakout record The Con, Tegan and Sara Quin, along with uber-indie producer Chris Walla, reveled in the darker recesses of indie pop, merging unconventional song structures and atypically diverse instrumentation with the kind of incisive, realistic lovelorn tales the two long ago perfected. Few would have expected the record to chart as well as it did, and it’s probably no coincidence that this, their sixth record, capitalizes on this. It’s perhaps the band’s most accessible to date, but these identical lesbian twins are hardly the likeliest candidates to be mainstream sellouts. Rather, Sainthood is a full-bodied, meticulously crafted rock record, one that stands firmly on its bedrock foundation of guitar, drums, and bass and lets the duo’s way with words and distinctive personalities shape the album into yet another uniquely Tegan and Sara album.
