I saw Chuck Mangione perform solo as a young boy, I remember his playing "Feel So Good" and being blown away by his sound; he's got such a smooth, soft tone on the instrument I also remember him just beaming with happiness like he is in these clips, great persona, which comes through in his playing. The flugelhorn lends to a softer tone but usually at the expense of sounding sad or mellow, but Chuck Mangione's playing is bright and ecstatic.
