"Game of Thrones" is an American fantasy drama television series based on George Martin's "A Song of Ice and Fire" and has received widespread acclaim by critics, although its use of nudity and violence has caused controversy. Filmed in Belfast and on location elsewhere in Northern Ireland, Malta, Croatia, Iceland, and Morocco, it premiered in 2011 and continues into a fourth season in 2014. The series interweaves several plot lines and through its morally ambiguous characters, explores the issues of social hierarchy, religion, loyalty, corruption, sexuality, civil war, crime, and punishment. It is set in a period that contains elements from the dark ages through to the medieval. The music for the series was composed by Ramin Djawadi and is noted for its popular main theme which is presented here as an arrangement for Brass Band. In keeping with the period depicted, the piece contains a significant contribution from the percussion section and care has been taken to achieve the desired effect with the normal resources of the average band.
