It was 2007, and while Led Zeppelin’s concert of the century was hitting the headlines, Robert Plant surprised everyone with the release of Raising Sand. This was an album of supreme beauty which saw the legendary rocker team up with the young bluegrass queen Alison Krauss. The duo caused a tidal wave, winning five Grammy Awards, including Best Album of the Year.  Fifteen years later, the two artists finally reunited on Raise The Roof, a collection of finely selected covers, ranging from mystical blues, and pastoral Americana to graceful folk. A subtle, unparalleled combination of the voice of an immaculate angel and that of an untamed lion. Alison Krauss, the most Grammy-winning female artist, will perform in Montreux for the first time. As for Robert Plant, this will be his fourth concert at the Festival.
