Yes I do ballads, in fact that's where the real expression is. But I don't enjoy them as much because (a) ballads tend to be background so people don't dance or pay as much attention, (b) it's harder (for me) to look like I'm into it, (c) people don't click on youtube links or vote in competitions to watch someone play a ballad :-)

I strongly believe that the performance of a song is at least as important as the song itself and I think that that belief has gained me quite a bit of business (and votes).
