I loved the first album, and am starting to get into the second one. It is not so immediately catchy, but definitely the Amy McDonald that we love.
There are problems with the 'deluxe' version. The online CD databases confuse it with the first album messing up track libraries, the case is only cardboard, but worst of all, the extra live album is a real disappointment. Amy tries to sing too deep for some reason, making most of the tracks sound ridiculous with the silly voice and distorted words distracting from the music. I don't know what she was trying to do, if the sound engineer was having a joke, she had a throat problem, or even if my CD is faulty. Someone commented that she was trying to sound French, or like Edith Piaf. I'm really not sure what is going on with that live CD.
I would recommend the normal version of A Curious thing, unless you want a laugh.
