Each of the four Fridays in June, Sean is playing us one opera of the Ring Cycle. Das Rheingold is first. I have Lego'ed the first scene already (See October 23, 2009). Below is the third scene of the opera, in the underground workshop where Alberich oversees the other dwarves as they create the ring and helmet out of the magical Rheingold.
This is of course the magic helmet of Elmer Fudd fame.
You can read more about the opera here. You can listen to the recording here.
