Jools Holland is headlining

Beginning on Friday, the jazz festival marks the start of a five week long celebration of arts and culture in Scotland's capital.

All styles of jazz by international artists will be heard at venues across Edinburgh from 25 July until 3 August.

Festival organisers are expecting a record-breaking season and predict 50,000 people will attend the jazz events.

World-renowned jazz star Dionne Warwick is due to perform live on Sunday in Princes Street Gardens.

Headline event

The 62-year-old is currently on a world tour celebrating 40 years in the music industry with hits like Walk on By and Do You Know The Way To San Jose.

Jools Holland and his Rhythm and Blues Orchestra, who are the headline event, will be performing on Monday night.

Elkie Brooks, the BBC Big Band and Chris Barber are also confirmed to play.

Two events over the weekend - Mardi Gras in the Grassmarket and Jazz on a Summer's Day in Princes Street Gardens - are free to the public.

The festival is the longest running jazz festival in the UK and marks the start of wider festival celebrations running throughout the month of August.

What many people refer to as "the festival" is actually eight different festivals, starting with jazz and ending with the Edinburgh Mela.

In between, there is the book festival, which this year features Sex and the City author Candice Bushnell, and the film festival.
