I am not the best person to ask about music. Indeed until earlier today, I had no idea what an intermezzo is. I like a number of different types of music: U2, Queen, the Good, the bad and the Queen, Bruce Cockburn, Show of Hands. I am not particularly into Christian music; but some friends of mine have a band called Freakshow. I do not know whether they sing my kind of music; but they are a group who are passionate about what they do and delight in singing about their love of their Lord Jesus. Their music is therefore more than a little infectious.
Here is a link to one of their pieces. Their lead singer tells me its a little rough, whatever that means.
