Rotterdam Summer Carnival 2025 aftermovie

Zomercarnaval 2025 aftermovie

⏳ Five weeks ago already!

Rotterdam Summer Carnival (Zomercarnaval) 2025 feels like yesterday, but time flies! For over 25 years (let’s just call it 30), Bjorn Ecury, the founder of Massive Pro AV, has been part of this amazing event: first as a DJ, and later with Massive Pro AV (formerly Massive Productions Holland), growing into the go-to sound partner for several groups.

This year we handled the AV for 5 floats/trailers for 5 different groups, the Rueda de Casino at Rotterdam Centraal station and the tech on the Soca boat.

🌟 And what a journey it’s been!
From diesel generators to green battery packs, from trucks and parade wagons to floats, from cargo bikes to complete sound set-ups, along all kinds of routes through our city… We’ve seen it all. Yes, including the restrictions we keep running into more and more as event organisers, sadly. But you know what?

🤝 One thing just keeps getting better.
The togetherness. The explosion of cultures from more and more countries taking part. The good vibes that make you forget the stress of everyday life. That Caribbean feeling running through your veins that lets you dream of sunnier places for a while.

🎬 That’s why we decided to make an aftermovie this year: to look back on another successful Summer Carnival 2025 and to capture this moment for the future. (Video credits: Day de Wijn 💕 )

❤️ Because it’s in our blood, right down to our bones. It’s who we are.
We’re already counting down to next year!


🙏 Our thanks go to Rotterdam Unlimited (Rotterdam Unlimited Zomercarnaval & Bureau Vermaeck) for keeping this wonderful event alive and organising it every year, to the more than 2,000 volunteers and, of course, to all the participating groups for their endless energy and creativity.

✨ They’re the ones who make Summer Carnival happen, with the crowds, the party and the magic.

And that magic… you feel it in every beat, every smile, every dance move.

See you next year! 🌴✨
