Tegan and Sara’s seventh full-length, last year’s Heartthrob,
is a sleek, synth-driven affair rife with the twins’ interweaving
vocals and enough hooks to power a dozen less-accomplished albums. It
represents the culmination of an evolution that has seen the
raven-haired Canadians move from Lilith Fair-nurtured, Indie Folk
upstarts to masters of perpetually heartsick Pop Rock.
