The Promenade concerts are concerts which are part of a big music festival.
“Proms” is short for Promenade Concerts.
The Proms are organized by the BBC, so they are called the “BBC Proms”.
They take place in the Royal Albert Hall, in London from mid-July to mid-September every year.
The Proms started more than 100 years ago, in 1895.
I would like to come to one of the Promenade concerts because the best musicians of the world play here.
