The Helsinki festival adds more names to its 2015 edition.

As part of their Electric World Tour, the Pet Shop Boys will be stopping off at Flow Festival, bringing their specially choerographed live show complete with visuals and light and laser show. Also added to the bill is hotly-tipped singer-songwriter Shamir, who is releasing his debut album on XL Recordings in May.

The new additions join a bulging line-up that already includes Run The Jewels, Todd Terje and Flying Lotus and performances from Tyler, iLoveMakonnen, Diplo, Róisín Murphy, Wiley, Evian Christ and more.

The festival takes place in the industrial setting of the former Suvilahti power plant in the Finnish capital of Helsinki from August 16-18. For full details and ticket information, check the Flow Festival website.
