When you think about Irish rockers, who comes to mind? Prickly, ginger-haired Van Morrison, in a near-transcendental state, wailing G.L.O.R.I.A? Bono in his wrap-around spaceman shades, righteously pouring out arena anthems with his U2 mates? Sinead O’Connor ripping up a picture of Pope John Paul II on “Saturday Night Live”? Well, there’s more to Ireland’s rock scene than that, boyo. On this St. Paddy’s Day, allow me to share a few of my favorite songs by several Irish artists who are lesser-known to American audiences.
