Q104.3 has streaming video of Logan Plant's band Sons of Albion's show tonight from New York. You can watch it here:
Embedding is not available yet, when it is I will embed the video.
Update for Nov 6: Embedding now available.
The young Mr. Plant doesn't sound a whole lot like his father, although the occasional hint is there. However, he has his dads on stage mannerisms. And, apparently, the old mans historical sense.
Overall, the band is pretty solid, Logan Plant not a bad singer. And stay with it until the end, because they absolutely nail Neil Young's After the Goldrush as the last song of the set.
