Niki & Donna forever (Images by Matthew Rettenmund)

The Niki Haris & Donna De Lory show at the Green Room 42 here in NYC was smashing!

The ladies, who are Madonna's former backup singers — and let's be real, backup dancers, too! — have a unique vocal chemistry they continually refer to in their act, but that you'd recognize even if they ignored it. Their voices blend so perfectly, making anything they sing powerful and uplifting.

Accentuating the positive is second nature to them, as is honoring their musical legacy. Along with their own songs (solo and as a duo), the women offered powerful renditions of “Open Your Heart,” “Rain” and “Nothing Really Matters,” and promised a future Q&A to further appease their Madonna-loving fanbase.

I was delighted when Donna impulsively sang a bit of her fabulous single “Just a Dream,” having already fully aired Praying for Love with Niki's backing and Niki's a true comedy queen. The women emphasize spirituality, yet not of the square kind — Niki was pulling a Moms Mabley from time to time. I LOLed when she pondered whether, in her 60s, It's just me and these labradoodles.

This show — produced by Jess Rothschild — follows one several years ago that came to the East Coast via a small club in Brooklyn, but it's far more polished, more of a rock show and more fully formed. 

They just get better, a good sign for whatever comes next. 

P.S. At the meet-and-greet Niki said she'd see me Monday at Madonna's Celebration Tour at Madison Square Garden. So whether they wind up merely attending or taking the stage, simply having the dream team share air once more will be a treat long in the making.
