A haggis is a tasty Scottish dish consisting of sheep heart, liver, and lungs, mixed with oatmeal, onion, suet, and spices, and then boiled inside a sheep's stomach. The Canadian-Scots band Enter the Haggis (bagpiper Craig Downie is from Scotland) has just about as much variety in their style -- a high-speed collision of Celtic music, rock, bluegrass, funk, and world music. An Enter the Haggis live show is a musical feast -- dynamic, emotionally uplifting, and intellectually stimulating. The band's music darts effortlessly from the traditional strains of the Chieftains and the Pogues to the frenetic pop of early Elvis Costello and even to Latin and African sounds. Enter the Haggis appeared last January at the Ann Arbor Folk Festival, and their busy schedule since then has included a tour of Ireland.
