Editors’ Notes Once a shocking new and innovative group, Cornershop have settled into refinement mode, enjoying the fruits of their early creativity by exploring their own sound at greater length. The addition of Bubbley Kaur puts an emphasis on Punjabi pop. The songs are not often sung in English, so the sound to American ears is one of even greater mystery. The grooves are measured, oddly calming, as Kaur sings like a pop matinee idol. “United Provinces of India” and “Topknot” are relatively sedate offerings before “The 911 Curry” balances electronica influences with the group’s Middle Eastern flavors. “Natch” and “Double Decker Eyelashes” continue the trip-hop-to-Brit-pop-to-Punjabi-pop experiments. Not unlike moments on their previous releases, Handcream for a Generation and Judy Sucks a Lemon for Breakfast, The Double-O Groove is a mix of disparate elements that comes together with surprising ease. These are dance tracks — “Supercomputed,” “Don’t Shake It,” etc. — intended to keep people moving to the multi-cultural groove.
