The musical traditions of Scotland are fused with the dynamic drive and electronic instrumentation of contemporary music by Capercaillie (pronounced: Kap-ir-kay-lee). While their initial repertoire focused on traditional tunes collected from Christine Primrose, Flora MacNeill, and Na h'Oganaich, the group has increasingly incorporated modern influences. In a review of their 1999 album, To the Moon, Victor Arenas wrote, "It has been more than a decade of a constant evolution, of modeling their traditional past with those modern ingredients that have made of their music that for which no doubt they will be known in the future."
