I don't have any idea about the mentioned artist. Though keep two things in mind --
The CA mics will capture whatever you hear, and even more, while still maintaining a relatively consistent frequency response (i.e., you won't be significantly losing any aspect of the sound at most recording-levels). If you're not satisfied with the levels, use an audio program to (carefully) boost them in post.
The second thing is, the High Sensitivity setting is quite noisy, hence you'll get a noisy recording when trying to boost the levels in post (should you need to do this). I also remember Guysonic or someone else had mentioned this point in the PCM-M10 big threads, suggesting (IIRC) not to use this setting, basing their suggestion on measurements they've done.
The cleaner your signal be at any level you record, the happier you will be afterwards.
