You can just see his dejection as he realizes he's the lead guitar in 'Hedgeclipper'
A hedge clipper or hedge trimmer is a gardening tool for trimming hedges or bushes. The implication is that motor driven hedge trimmers produce a bad, loud sound; maybe the sound of the band is even worse. Additionally, each member of the band has a haircut that resembles a trimmed hedge.
The title text suggests that they (or at least the lead guitarist) previously did not know their band's name. As he bemoans his apparent inability to choose a good band name, he probably sees the name 'Hedgeclipper' as the reason why the band has no audience.
