It's been three excruciatingly long years since we last heard new music from Adele.

Adele's done a lot of growing up since. She's a mom now! And after months of writing and recording and endless rumo(u)red returns, she finally, officially poked her head out of the studio with "Hello," the first offering from her forthcoming album 25. (She's 27 now, but hey, life happens.)

The gorgeous piano-led production is chilling and appropriately dramatic, especially as the backing vocals fill out the song toward its crashing finale. But at its core, "Hello" is Adele delivering what Adele has always done best: Raw emotion, thunderous vocals and an ability to cut deep, making the most common, otherwise friendly salutation send a tear or two rolling down the cheek.
