The 4th rehearsal is by the group SUDDEN LIGHTS from LATVIA. Their luggage got lost in Germany so the band rehearsed in their day-to-day clothes.
According to Eurovision.tv, it was time for another band (after Malta), and it’s Latvian alt-rock 4-piece Sudden Lights with their song Aijā. The song is sung in English but the title is in Latvian – apparently Aijā doesn’t have a direct translation, but it evokes the feeling of a Latvian folk song.
Hopefully the Latvian entry will make it to the final.
Stephan Herholdt designed a promo CD single for ESC Covers and here you can see it.
