More than 80,000 are expected to descend on Gunnersbury Park on Sunday to take part in this year's London Mela.
The event – which is Europe's largest South Asian festival – returns with a spectacular line-up of live music, dance, visual arts and food from South Asia.
The family event is free and produced jointly by Ealing and Hounslow councils, with the support of the Mayor London.
The first London Mela took place in 2003 and attracted 60,000 people. But such was its popularity that the following year's event pulled in a crowd of 90,000. Sunday's London Mela will feature nine zones, making it bigger than last year, with attendances expected to top the 80,000 mark set in 2013.
It will be an artistically led celebration of Asian culture and creativity, featuring the best in classical music, British Asian urban artists, dance, comedy and cabaret, Asian-influenced street theatre and circus, and exhibitions.
Among this weekend's highlights will be bhangra superstar Miss Pooja, desi-reggae artist Cold Fever, female viral sensation Nesdi Jones, and British Pakistani heartthrob Junai Kaden.
The London Mela takes place between 1 and 9pm. For more information and a full line-up go to www.londonmela.org
