Through exclusive interviews and over a decade of deep research, renowned music journalist Jan Gradvall explores the secrets to ABBA's success.

More than half a century after their songs were recorded, ABBA still make people the world over dance and sing their hearts out. After interviewing the four members for an article in 2013 - at which time the band had not been interviewed for over thirty years - Jan Gradvall was granted unique access to them for the next decade. In The Book of ABBA, the band share their thoughts and opinions more openly than ever before, while Jan reveals the context in which their sound developed - and shows how the story of ABBA is also the story of Sweden and the globalisation of pop culture.

From their chart-topping ABBA Voyage - their first album in forty years - to the two-million-ticket-selling concert-experience of the same name, it is undeniable that, in the history of pop culture and music, there has never been a group like ABBA. With remarkable intimacy, Gradvall's book brings readers closer than ever to one of the world's most notoriously private music icons.
