Darkness shrouded Rockwood Music Hall, and barely a flicker of light illuminated the figure on stage. The silhouette was Melanie De Biasio, a native of Belgium, and tonight was her first performance here in New York City, a private event hosted by her label, PIAS. Joined by Pascal Paulus on guitar, she wove through a short set of material showcasing her second record, No Deal. It’s very chilled out, sultry music, and above all, personal in nature and delivery. No idea when she’ll be return, but there will be a lot of clubs vying for her attention upon it.
