"Generosity," the opening song of Mirah's new album, is as beautiful as anything the K Records singer-songwriter has ever recorded. The sad, spent lyrics suggest Shel Silverstein's classic The Giving Tree. The arrangement includes stately strings, deeply resonant piano, martial drums, quietly distorted guitar, and a chorus of singers led by Mirah, whose voice is whisper-soft and utterly commanding, always pitch-perfect. Mirah has a catalog over a decade deep, from the four-track pillow talk of You Think It's Like This... to the orchestral song cycle about insects of Share This Place. With Lovers and Whitney Ballen.
