First rehearsals continued in the Rotterdam Ahoy, with 9 more countries from the second Semi-Final performing their songs on the main stage for the first time.
You can read the full Day 3 Live Blog, as it happened, here, and we're back tomorrow at 10:00 CEST for Day 4.
We got off to a banging start this morning with Senhit from San Marino rehearsing her song Adrenalina. It featured Senhit in an elaborate crown and alien dancers in red boots, but no sign of Flo Rida yet. Is he coming? We'll just have to wait a bit longer to find out.
Next up was Uku Suviste from Estonia, who delivered a heartfelt vocal performance of The Lucky One. The stormy graphics and underwater video created an intense atmosphere for this classy ballad.
Next up on the main stage was Benny Cristo from the Czech Republic, who brought his trademark energy and a very sparkly yellow jacket to his slick performance of Omaga. We can't wait to see what a live crowd brings to his performance during the second Semi-Final next week.
The final performance of the morning session was Stefania from Greece, whose performance of Last Dance took place in parts against a green screen and remains shrouded in mystery. We saw her fabulous purple catsuit and her four male dancers, but all we know about the rest is that it's something that's never been done on the Eurovision stage before! How exciting is that?
After lunch, Vincent Bueno from Austria brought a black sequinned jacket and a compelling vocal performance to Amen, with the bare minimum of graphics and props. It may have been simple, but it was also hugely effective.
Poland were up next, and Rafał took us back to the 1980s in the best possible way for The Ride. It had lights, geometric graphics, torch-wielding dancers and Rafał in his signature sunglasses and leather gloves. Definitely a ride, and we're not sure we want to get off.
Natalia Gordienko from Moldova kept the tempo up with her song Sugar. It was the biggest surprise of the day, taking a huge step away from the sugary theming of the official video. Instead Natalia and her four dancers brought a touch of black and silver glamour to the main stage, with the pink reserved for the graphic backdrop.
From the glitz and glamour of Moldova to the pixel jumpers of Iceland, with Daði og Gagnamagnið delivering a joyfully dorky performance of their song 10 Years. Have you learned the dance routine yet? If not, why not?
And finally on the main stage today, Hurricane from Serbia brought their own unique brand of Loco Loco. Glittery black dresses, fireworks, steam - this performance was the perfect way to finish off another amazing day of live music in Rotterdam Ahoy.
We'll wrap up first rehearsals tomorrow, with the final eight acts performing in the second Semi-Final taking to the stage.
