Kate Nash is the rare performer who will let you see her as a whole person. In a sold-out performance at the 9:30 Club on Monday night, Nash was by turns angry, quietly funny, rambunctious, vulnerable and always charming. Simply put, Nash wants you to know her many sides — and that they compose one person who will kick your ass.

Entering to crashing thunder, under clouds that looked suspiciously like pillows and lightning bolts that could have been made from cardboard, the set was a delightful contrast of punkish rage and girlish sentiment, the clever middle ground that so many wish to strike. Speaking to her fans, her English lilt offered politeness, but each number, with its volume and conviction, gave a sense that she wanted to tear you apart. Well, almost each number.
