After Hours host Patrize announces guest DJ Chaum for 483

After Hours 483 on Scientific Sound Asia features PatriZe alongside guest DJ Chaum. Scientific Sound Asia is an underground electronic music radio station, DJ agency and promoter serving the Asian region and beyond, publishing music news and connecting audiences regionally and internationally.

PatriZe is a Belgian DJ, producer and label head whose early interests in trance and techno gradually gave way to the melodic structures of progressive house. That transition has shaped both his DJ sets and his studio output ever since.

His path into the wider scene began in 2010 through a working relationship with Pole Folder, an artist connected to Bedrock Records and Reworck. That same year he won the Night Museum DJ competition in France, taking an opening slot for Guy J that helped establish his name beyond Belgium.

Behind the decks, he builds through layered melodic arrangements and unhurried transitions, with a quiet tech thread running beneath. Based in Thailand, he plays regularly at Beachspot and Thai Lounge & Terrace in Pattaya, maintaining a steady local presence alongside his international radio work.

He co-founded AH Digital with Hypnotised in April 2015, a label centred on progressive house that has worked with artists across the genre. The debut EP People from the Otherworld reached number four on the Beatport Progressive House chart and broke into the top twenty in both techno and tech house.

Recent collaborative work with Hypnotised includes a remix of Michael A's Ignition on AH Digital from early 2025 and multiple releases of their Nikoow's Weird Things rework across late 2025 and into 2026. His 2023 DJ mix AH Digital Essentials 004 offers a broader view of his range, threading through house and techno across an extended session.

Guest DJ Chaum.

Chaum is the alias of Angelo Moutsai, a DJ and producer from Patras, Greece whose sound sits at the intersection of progressive house, melodic techno and deep house. He began playing music in his teens, and his first release came shortly after as Angelo M, a remix of Mikalogic's 82 Love You.

As his production skills developed alongside his audio engineering work, a darker and more textured aesthetic took shape and the Chaum identity emerged. His Beatport catalogue spans labels including Sudbeat Music, Lowbit, 3rd Avenue, BC2, Krafted Underground, Future Avenue and Juicebox Music among others.

A long-running collaborative relationship with Hobin Rude has produced originals including Cressida and Mesec on Juicebox Music and Back and Forth on Sudbeat, with Cressida in particular appearing across multiple releases and drawing a remix from Tonaco. His remix of Lupe Republic's We Are Together has similarly been released across 3rd Avenue and The Audio Atelier at different points, pointing to tracks that have found sustained traction within the scene.

Remix credits have come from a wide range of artists and labels, with work for Geolo Berlange on Future Avenue and The Audio Atelier, Hernan Cerbello on One Of A Kind, Benja Molina on PURRFECTION and Anton Stelsi on Lowbit among the more notable. His sets carry the same qualities as his productions, blending softer melodic elements with deeper rhythmic movement and an underlying darkness that draws the dancefloor in gradually.

After Hours 483 opens with PatriZe drawing from a range of Progressive House labels. FJL's Dayglow on Or Two Strangers sets a warm and melodic tone before Fabri Lopez's Dubbel in the Forerunners Remix on Massive Harmony Records develops the mood.

Daniel Testas's Crumbling Silence in the Ric Niels Remix on MNL and DJ Paul (AR), NAHS and Andre Moret's Experience on Soundteller Records carry the hour forward. Monojoke's Pearls in the Kostya Outta Remix on Nature Rec and Deeparture's Propellor in the GMJ Remix on Clubsonica Records sustain the progressive direction through the mid-section.

Mattias Herrera's Elephants in the Juan Ibanez Remix on Future Avenue and German Tedesco's Naipi in the Agustin Lupidi Remix on One Of A Kind carry the hour into its later stages. Juan Ibanez's Ariad in the André Moret Remix on SLC-6 Music and Claudio Cornejo (AR)'s Musai on Clubsonica Records bring PatriZe's ten-track hour to a close.

Guest Chaum opens the second hour with his own Memories on The Purr before Ayala (IT)'s Levante on Sol Selectas introduces a warm Organic House quality. Pedro Capelossi and Leon Lobato's Down The Rabbit Hole on Loot Rec and Enamour's Compelled sustain the organic warmth before Beije's Azimuth in the GMJ Remix on Sound Avenue returns to progressive territory.

Vlad Jet's Terra Nova and Chaum's Deka Ennea on Harabe, a track that has appeared across several After Hours episodes, carry the hour into its later stages. Aman Anand and Chaum's Turmoil Paintings on Mango Alley gives the host a collaborative moment before DP-6's Resolve in the Aman Anand Remix sustains the connection between the two artists.

Chaum's Dyan Moon on Soundteller Records closes the episode, the host bookending his hour with original material and rounding off a second hour that balanced personal selections with carefully chosen guest tracks throughout. After Hours 483 is a cohesive two hours, PatriZe's South American label network giving way to Chaum's more intimate and self-referential guest selection.
