LONDON - The first ever map showing the locations of over 1,000 music spaces in the British capital was published Thursday by London Mayor Sadiq Khan.

Khan's map comes after new research showing that after years of decline the number of grassroots music venues in London is now stable.

The map shows the full spectrum of music performance, recording and rehearsal spaces in London, highlighting areas of opportunity and growth.

The research has so far found more than 1,000 venues in London hosting a regular schedule of music. They include 94 grassroots music venues, 38 musical theaters and over 500 pubs and bars. It also mapped 75 recording studios, 83 rehearsal spaces that contribute to London's music scene.

The research report says: "London is the home of the UK music industry which contributes 4.4 billion pound ($5.9 billion) to the UK economy and sustains 142,000 jobs. The music industry plays a vital role in London's position as a global cultural capital, and this new and far-reaching approach represents a fantastic new opportunity for musicians all over London and beyond."

Mayor Khan said: "London has a great musical heritage but it's not something we can take for granted. If we don't support our grassroots venues and fail to support facilities for emerging talent, then we're putting the city's position as the music capital of the world at risk."

London boroughs, developers and music operators will now be able to see the areas where musical activity is most concentrated, or where more facilities of a particular type, from music performance and rehearsal spaces to recording and production spaces, are needed.

Many venues where people go to see the latest bands or theater shows are located in central areas of London, such as Camden, Westminster, Islington and Hackney, but rehearsal or recording spaces are much more likely to be based in outer London areas.

Justine Simons, deputy mayor for culture and creative industries, said: "The new research and map really goes to show that music is in every corner of our city, from a live-mic night at your local pub, to the Rolling Stones at the London Stadium. Our wide grassroots music venues and studios are at the heart of our success as a global capital of culture."
