We're delighted to announce the fourth release on the Expert Sleepers label, "Crossing the line" by Expert Sleepers' own Andrew Ostler. Available as a digital release and as a 12" vinyl LP.

“The sonic equivalent of enjoying a cigar in your leather-upholstered vintage car while hurtling down the autobahn. Unashamedly nostalgic for the polyrhythms of ’70s Berlin school, yet infused with contemporary drone sensibilities and lifted by soaring solo lines.”

Listen and buy on Bandcamp.


Expert Sleepers make Eurorack modules, and other synth hardware. We also make VST, AudioUnit and AAX plug-ins for macOS and Windows, as well as plug-ins for VCV Rack.

We also run a small music label on Bandcamp, showcasing artists who use our products.

"Instruments that sound good inspire better music, and it's a struggle to make music with bad-sounding instruments, irrespective of how talented you might be.

"I don't know enough about programming to understand why some software tools fascinate you while others make you want to get another job, but I do know that when I use anything by ES I get excited by what I'm hearing. These tools have the sonic richness of great analogue instruments - with the features of innovative digital ones."
