Question three, Wagner versus Liszt.
Just my opinion, but I like Wagner and rate him considerably higher than Liszt, but that is not to say Liszt is poor.
Liszt is best known for his piano works. The Hungarian Rhapsodies are a good place to start.
Wagner composed almost solely operas, but these are generally massive works. The Ring Cycle, made up of four operas, is an amazing event. More than 15 hours of music over four days, and a story involving giants, gods, etc. It is hard not to be impressed after seeing a ring cycle (I have been lucky enough to see two on stage).
Ken obviously likes Liszt. But Wagner? I suspect not.
