Durham Brass Festival audiences topped 40,000 as the 2019 event became the most attended year to date.
Cllr Joy Allen, cabinet member for transformation, culture and tourism at Durham County Council said: "Over the last 10 days the excitement and magic of brass has spread to towns and villages across the county and I have been blown away by the response we have had.
"It has been wonderful to see people of all ages – from young school children to older care home residents - being uplifted and inspired by brass music.
"The free parties in streets and parks brought communities together, while also attracting visitors and boosting the economy. That is why investing in the arts is so important; it raises aspirations, creates a sense of civic pride and builds on County Durham's reputation as a cultural destination."
The 10 day Durham Brass Festival began with a secret brass gig, where regular band Mr Wilson's Second Liners played brass arrangements of 90s club classics at a venue that was only revealed once people had booked their tickets.
The programme of concerts also saw very different styles of concert, such as Verdi's Requiem at Durham Cathedral.
Meanwhile Oktoberfest saw Durham Town Hall transformed into a beer hall for an evening of German food and music to mark the 50th anniversary of Durham's twinning with Tubingen.
The free Wharton Park brass concerts also returned for the 2019 Durham Brass Festival, including the Big BRASS Party and Wharton Park meets the West End, both on the final weekend of the festival.
