I like the Velvets and Leona.
OK, I like the Velvets a lot more, and I've only heard two Leona songs, but it would be difficult to argue she's a bad singer.
btw Dezb - Have you heard Boom Bip? Don't want to teach you how to suck eggs, but he's very similar to Subtle.
Saw him playing Royal Festival Hall supporting Tipsy a few years back. Two more musical treats the US have given us.
