The NaveBlues’ “Sitting On Top Of The World” is a powerful, impassioned take on the Doc Watson classic. Little more is needed during this performance than a set of vocals and a piano. Together, these two elements combine to make something tremendously effecting. When the harmonica enters into the fray, everything is ratcheted up to ten. The ferocity and emotional content of the track is impressive – all parts here are given their own time to shine, and the resulting effort is made all the more impressive because of it.
