A unique day-long celebration of music is under way in Londonderry.
Music City is one of the biggest events in the UK City of Culture programme.
Concerts, festivals and performances are taking place from dawn on Friday until dawn on Saturday.
The celebrations began with a dawn chorus at an ancient stone fort in County Donegal, and were followed by the Sky Orchestra - seven hot air balloons that played music as they floated above the city.
