Lúnasa – The Merry Sisters of Fate

Lúnasa built their sound without percussion, using Trevor Hutchinson's double bass and Donogh Hennessy's guitar as an elastic rhythm section under three melody players: Kevin Crawford on flute, Seán Smyth on fiddle and Cillian Vallely on pipes. On this 2001 album the leads trade counter-melodies and lock into unison runs with real precision. Choose it for the most modern-sounding groove on the list.
