Jenny Hollingsworth is one half of the consistently interesting and often great UK alt-pop duo Let’s Eat Grandma, and now she’s making solo music under the name Jenny On Holiday. Perhaps she’s on holiday from eating Grandma. Last month, Hollingsworth released “Every Ounce Of Me,” her first Jenny On Holiday single, and I thought it was fantastic. Now, she’s ready to announce her first solo album. It’s called Quicksand Heart, and it’s coming out at the top of next year.
