My most favourite performers are those who either sing unaccompanied or accompany themselves. Next are those who work with a sensitive accompanist who can support and follow the singer.

My least favourite performers are various 'bands' and 'folk choirs'. It seems to me that such 'collectives' are only interested in their overall 'sound' and not very interested in the content of what they are doing. It may be that what they are attempting to do is difficult and/or demanding technically - but I rarely find it very interesting.
