Something a little different for you on our latest episode of Soundtracking, as Edith speaks to Baillie Walsh. Baillie is the director of the extraordinary virtual concert, ABBA Voyage, though to call it a virtual concert really doesn't begin to describe quite how spectacular it is. Made in conjunction with the band, it features incredible life sized avatars - or ABBAtars - a mind-blowing light show and sensational live band, and is a full-blown assault on the senses in the best possible way.  As a show, it also raises questions about the future of gigs - and how big tours can be more sustainable.
