Interactive Hybrid DJ

DJ for weddings, corporate events, parties and clubs across Finland

DJ Justin Case on stage, crowd with hands up

On stage since 2002.

DJ, performer, MC.

I play, perform and host, and get the crowd singing along when the moment calls for it. I don’t hide behind the DJ booth.

I turn familiar songs into my own mixes that keep the dance floor moving. I read the crowd all night, so every night is its own.

I have been on stage since 2002, at more than 1,200 events from major Finnish festivals to club residencies in Helsinki, Tampere and Levi. I have also played in Sweden, Bulgaria and Belgium. Big stages, private events and weddings are all part of the job. You’ll find upcoming shows further down this page.

Weddings & parties

An interactive wedding and party DJ since 2002.

“Peik played at our wedding and left no one cold! He played exactly the music we wanted, with a little twist of his own. He read the room and the atmosphere was through the roof. I warmly recommend him! Thank you for making our celebration unforgettable!”
Aki M.Wedding · Google
“An absolutely brilliant wedding DJ! The music was just right for the guests and our requests were taken well into account. Great instincts with the music throughout the evening. The compliments kept pouring in. I can't do anything but recommend him!”

Client feedback is given on a feedback form that I send to clients after a booking. I publish feedback only with the client's permission and only after checking in my booking calendar that it concerns a booking that took place. I publish all such feedback regardless of the star rating, except content that is offensive or contains other people's personal data. Google reviews are public reviews on Google, and their authors have not been checked as clients. Google review quotes are translated from Finnish; client feedback is shown in the language it was given.
