American singer/songwriter John Grant, Dublin's own Imelda May and British indie folk band Stornoway are all on slate to perform at Other Voices' London event, which spans from April 5 to 7 at Wilton's Music Hall.

The artists join several other confirmed acts for the event. Stornoway, who just released Tales From Terra Firma, will play on April 5 along with singer Laura Mvula. On April 6, John Grant and Imelda May will perform in addition to previously confirmed Dexys. The event will wrap up with a performance by American musician Matthew E. White on April 7.

Due to the limited amount of space, Other Voices will be streaming the acts in several other London venues. Oliver Conquest, the Zeppelin Shelter, the Princess Alice and the Barbican Camera Cafe & Bar will all being streaming the event. There will also be online streaming.
