[2] Each broadcast is uninterrupted by back-announcing other than near the beginning and end of the show, and consists of a 90-minute musical soundscape created by segue mixing tracks from a number of different artists.

Initially launched as a 90-minute programme, the duration was expanded progressively to two, and then three hours, until settling back into a 90-minute slot from March 2001.

Towards the end of 1998, David Bassin, Candace Cappe, Victor Kay and Nev Dorrington joined Cruickshank as co-producers, although that arrangement proved impractical, and was terminated early in 1999.

[5] A third station in the Fine Music Network, Artsound FM, Canberra, began to carry the show in November 2006, broadcasting it on Tuesday evenings from 10.00pm.

Chasing the Dawn: Ultima Thule Ambient Volume 01, a branded compilation album produced by George Cruickshank, was released as a fund-raiser for 2MBS in early 2006.

It features original and previously unreleased compositions by thirteen ambient artists, including Steve Roach, Tim Story, Robert Rich, and Numina.
