The second thing you notice about Lizz Fields’s debut album bydaybynight, besides Fields’s beautiful voice, is how much farther she could have taken it-but didn’t. The self-produced CD has some high points; on opener “I Gotta Go,” Fields shows some great nuance, and “Star Gazer” is solid on all fronts. But many of the songs sound too alike, treading and re-treading much of the same territory. It’s souled-out and mellow ground, yes, but you still wish for something to help Fields take that one more step into greatness; she sounds like she could have it in her.
