22. Ba Ba Ti Ki Di Do – Sigur Ros (2004)

As their last album, Með suð í eyrum við spilum endalaust, seemed to resign Sigur Ros to what we expected of them – that being purveyors of grandiose, symphonic post-rock – it makes under-the-rug releases like Ba Ba Ti Ki Di Do that much more interesting. Even without the Icelandic group’s slow plateau, this EP of songs composed for Merce Cunningham’s Split Sides rivals their best full-lengths. However experimental and unfurling, the melodies at work throughout these twenty-minutes ebb and flow, sympathize and dominate in turn, as Sigur Ros’ best ambient work to date.
