I went to the Harry and the Potters show looking forward to seeing the opener Draco and the Malfoys. If you listed to CDs from both bands Draco clearly stand out as a better band. They have song that are about the Harry Potter books while Harry and the Potters often sound like they are just reading out of the books.
Draco and the Malfoys were great. With just 2 guitars they played the drum track off their laptop but that did not stop them from having a great energy.
I was blown away by Harry and the Potters. While they don't sound that great on a CD they are amazing live. Their songs are great for singing along to and the audience was on their feet jumping around for the whole set. I can't really explain the energy they had so instead take a look at the video.
If you ever get the chance and you have any interest in Harry Potter I greatly recommend stopping by a show.
