There is more than one artist with this name:

1) Heron is a British folk band from the 1970's who originally put out two albums on the Dawn label.

During the post psychedelic era for folk music many bands fused together delicate melancholia with a simple folk basis. Heron like Waterfall, some Magna Carta and Dulcimer fall into this area. Some would say that it derives from Simon and Garfunkal but this seems to be less story based than their music and more introspective. Heron bring guitar, banjo and keyboards such as acoustic or electric piano to provide a fairly unique, gentle sound that seems to work late at night or early in the morning as a kind of slightly sad background music. Looking back we might place it closest in intent to the music Nick Drake wrote and performed so definitively. If the music doesn't scale the heights of that unique artists then in truth not much actually does but this is not to dismiss the merits of the music here.

2) Heron is a hip‑hop/rap artist from NYC.
