From the opening seconds of “Life Is,” it’s clear that Here in the Pitch is a very different kind of album from Jessica Pratt. The revered Los Angeles artist has become one of the most singular and distinctive songwriters of her generation, largely through the bewitching sound of her acoustic guitar and vocals: a mystical, elusive blend that conjures deep emotional responses from her devoted (and patient) audience. To introduce her first release in half-a-decade, however, she greets us with neither her breathtaking vocals nor the delicate, sophisticated strum of her guitar. Instead, Pratt’s fourth album begins with a percussion roll that nods instantly to the grand, orchestral style of ’60s pop hits like the Walker Brothers’ “The Sun Ain’t Gonna Shine Anymore.”
