The new Version 3 of dreamSTATE's multimedia iAlbum of ever-changing ambient music and urban ambient art can now be used by both Listeners and iMusicians:

(1) For Listeners - A new infinite music arrangement is created for a unique sonic experience every time Ephemeral City is played.

Lose yourself in the endless drift of the ephemeral ambience, while walking through your own city, while reading, working, creating, thinking, relaxing or sleeping. This iAlbum can also play in the background while you read your e-mail or e-books or browse the net.

While Ephemeral City weaves a fresh musical arrangement for you every time, you can adjust the density of the mix from a rarefied atmosphere to a full-on flow or from the dark to the light. Set the Timer to define the length of the album. Adjust the speed of the visual transitions to reveal new fusion imagery.

(2) For iMusicians - Open Ephemeral City as an Inter-App Audio (IAA) Generator/Instrument in your favourite "host" applications (like Audiobus, Aum or apeMatrix) and process the infinitely evolving Ephemeral soundstream through your Effects apps to transform the audio into creative variations, for your own pleasure or for professional purposes.

Improvise or compose with the endless soundflow. Treat Ephemeral City as the ultimate textural drone oscillator. If you record your creations, dreamSTATE permit you to release your transformations under the most open creative commons attribution 4.0 license.

(Art) Place your iPhone or iPad in your speaker dock to display the evolving visual art of Scott M2's surreal cityscapes. Employ the mute button for a pure art experience or turn off your screen for a pure musical experience.

Trailblazing Canadian soundscape artists dreamSTATE (Scott M2 and Jamie Todd) created their first evolving ambient installation in 1996. Now, with the help of ReFla5h the Apptician, they've created an infinite multimedia ambient installation for your iPhone, iTouch or iPad (with iOS 8.0 or higher).

Welcome to a new paradigm for albums - experience Ephemeral City now.


- A Tour Guide page walks you through the controls - or just let the iAlbum play.

- The Control Panel gives you the option of adjusting the music mix and the speed of the visuals.

- An optional Timer can turn off the music after 15 minutes or up to 8 hours.

- Your Mix, Visuals and Timer settings are remembered between visits.

- A speaker icon mutes or restores the sound without adjusting volume buttons.

- The ambient art continues to evolve when the sound is muted.

- You can turn off the screen for long battery life during extended deep listening sessions.

- An Info section contains bios for the creators and links to more dreamSTATE music.

- Plays on any iPhone, iTouch or iPad with iOS 8.0 or higher.

An absolute gem

The App Store is full of generative apps for creating music without direct input, or with minimal user control. Most of them are limited in scope or grow stale and static with extended listening. this beautiful album stands in stark contrast to that.

While its visuals are beautiful, I believe that the true strength of this app lies in its continuously evolving and seamless musical creation. Its character constantly changes, yet it retains a certain thematic wholeness. i’ve been doing ambient music for decades, but I must tip my hat in respect to the creators of this gorgeous app. If you’re looking for a way to relax, meditate, or even just fall asleep with the aid of gentle and fascinating music, you need to take a trip to this Ephemeral City.

Ambient playground

Ephemeral really shines as an ambient sound generator. Very lush pads morph over time and create a seamless soundscape. IAA allows it to play nice with other apps. It would be great if patch creation and save features were available. Greater mixing options and import of user samples would be nice as well. As is, it is one of the most musically useful ambient apps on the market. Kudos to the developers!

Terrific dream state app

I am an Ambient musician and artist myself, so I completely "get" this work of conceptual art. Visions of melting cityscapes come and go as you listen to cleverly-programmed ambient soundscapes. In older times I could imagine this being a room in a gallery with projectors running and a loudspeaker installation. If you consider this less an app and more of an artistic statement you will approach the intent of the creators.

I like to use this app late at night, when it seems like you are drifting through a dream city where you are the only inhabitant.
