Guest DJ (first hour) Praveen Jay.
First-hour guest Praveen Jay was described as one of Sri Lanka's most in-demand DJs and producers, with a strong profile in the country's electronic-music scene. He was rated as “Iconic” and among the island's top-rated electronic-music artists.
Praveen Jay built a following quickly through his knowledge of electronic music and performances for his fans. That demand led to appearances at mainstream events and beach raves centred on electronic music.
His commitment to electronic music distinguished him within Sri Lanka's competitive electronic and underground scene. In its relatively short history, he established himself as one of the island's more prominent talents.
Having begun playing records at 17, Praveen Jay started as a freelance DJ and developed his craft through experimentation. His groovy and energetic style became central to performances intended to give audiences an expansive experience.
His enthusiasm for music, knowledge of the scene and understanding of its elements helped set him apart. Those qualities, alongside his personality, contributed to his progress in the industry and influenced younger DJs who followed his style.
Praveen Jay was presented as a trendsetter willing to experiment and bring emotional weight to each performance. By selecting up-to-date material from his library, he introduced new grooves to the dancefloor and kept audiences anticipating his next choices.
He also created the Sri Lankan underground-music community known as “DISCO DISCO”, described as a rising trend among new-generation partygoers. Its sound ranges through Nu-Disco, groovy deep tech and darker groove-oriented beats.
Alongside DJing, Praveen Jay is one of the relatively few electronic-music producers from Sri Lanka cited in the original profile. After releasing beat-led bootlegs and remixes, he began making original singles whose tracks and bootlegs gained demand internationally and within Sri Lanka's fast-paced electronic dance-music scene.
His productions have moved between uplifting House and Progressive House while also combining Tech House, Minimal Techno and underground Disco. He initially made his mark through remixes and bootlegs of highly anticipated material by high-profile artists.
Praveen Jay released his debut original single in 2012 and was focused on producing further groovy underground material. When preparing for a show, his stated aim was to take the crowd towards another state of consciousness through unexpected selections.
His floor-focused approach and output led to recognition as one of Sri Lanka's top-tier DJs . This guest appearance placed that approach at the centre of Petrichor's first hour.
Praveen Jay opened with Oliver & Tom's Gallardo on Tarnished Tracks, establishing a Progressive House direction. Chris Cargo's Coyote on Rounded then brought in a more melodic line.
Anakim's Alien in the Stargate, released through Desert Hearts Black, developed the Melodic House and Techno character. Betoko's Morttagua remix of Bitkoin on OKO Recordings returned the set to Progressive House before Stylo's Got Mine on Timeless Moment shifted the emphasis back towards melody.
Dizharmonia's Cherouveim, also on Timeless Moment, sustained that melodic house and techno focus. Gabriel Amato's Kenan Savrun remix of Anthrax on Movement Recordings restored the progressive pressure for the later stretch.
Matan Caspi's Rick Pier O'Neil remix of Behind You on Freegrant Music kept the later selection rooted in Progressive House, before Modeplex's Supacooks remix of Jaded on Kitchen Recordings pushed the same direction further. Space Motion's Da Fresh remix of Voices provided the final selection, closing a first hour built around melodic tension and progressive club music.
