A life in sound.
Some passions never switch off. For Den Jones,
audio is one of them. Welcome to the other side
of 909 — where it’s all about the music.
The person behind the sound
You might know Den Jones as the Founder and CEO of 909Cyber. But behind the security mindset is a lifelong love of all things audio — the records, the gear, the craft, and the feeling when a track just connects.
909Audio is a home for that passion. From the music of BigRoomDrama to tools that bring a mix together, this is where curiosity meets creativity. We’re just getting warmed up.
The music
Music made for the floor, the late hour, and the soul. Step into the sound of BigRoomDrama.
Meet BigRoomDramaThe other body of work
Separate from BigRoomDrama, this is Den’s own catalogue. It started on vinyl in 1994 as Future Nation with “I’m For Real” on Scotland’s Clubscene Records — the first record he ever released.
From 1994 to 1997 he wrote many of the songs for 90s rave band The Ultimate Buzz and founded Bass Instinct. The sound has evolved; the obsession hasn’t.
Den moved to California in 2001, and the remix desk came with him — reworking tracks for San Francisco’s Karmacoda and Momu, among others.
