My work involves music for theatre projects to invent a musical language with strategies. That is what is represented in my work. Yes, as it is very popular, in that at concerts at the Festival Hall both nights were sell- outs. It is not therefore played in small galleries, alternative galleries and late night clubs which were the venues in the early sixties and seventies. For example, popular music and pop music are very different things.
Pop music is examined in terms of record numbers.
For 1-10 million people, classical music may be popular but maybe only sell 100 thousand copies. Mainstream suggests that the music is enjoyed by a heterogeneous audience. That of different age groups, economic classes therefore not specialist. In the USA mainstream is Country and Western. People may see themselves as classical music lovers but may not hear a lot of music.
