Aoife O'Donovan (vocalist for Crooked Still in addition to her other projects and solo ventures) is one of my favourite female singers. I've seen her sing live many times and she is wonderful. A great talent who can work her magic on traditional songs and inventive cover versions as well as writing some superb songs herself. There are tons of clips out there in the ether but here's a sampling...
