On most tracks Faithfull sings pleasant and not particularly exciting - harmless and time-typical songs with friendly arrangements. It sounds as if Faithfull has almost incidentally also recorded songs - without full commitment. It can be seen already how good she could be and that their voice is excellent - but their qualities are not really fully maxed out.
Then they crashed with drugs and alcohol - and was totally changed and matured with Broken English etc. again. If the rough Faithfull second career section is expected to be a disappointment inevitable.
