In Brief

* * * Tori Amos, “Little Earthquakes,” Atlantic. Few have progressed from the silly to the sublime as quickly or smoothly as Amos. The North Carolina singer/pianist started her pop music career a few years ago as the leader of the underwhelming Y Kant Tori Read. Now solo, she’s delivered a quixotic, compelling record that mixes the smart sensuality of Kate Bush with the provocative impenetrability of Mary Margaret O’Hara.
