When traditional Irish music is wedded to mainstream influences, the emerald genes color the offspring. So it is on the second release by one of Ireland's more exciting acts. Saxophones, trumpets and other unexpected noisemakers sweeten several tracks, while jazz hints boost the octane level of some of the more rhythmic passages and horn improvisations. But these influences, negligible as they are, are overwhelmed by the band's self-contained, infectious and folk-derived energy. The proof of Irish music's endurance, even in these hard times for creative pop, abides in the sound and spirit of Kila.
