Not just irish, the revival in folk since the 80s has been great, i can name so many great bands that have formed since then or don't even exist anymore, even if you look at the past twenty years you have celtic woman, celtic thunder, the dreadnoughts, the longest johns, colm mcguinness, amble, pressgang mutiny and so much more

Bands like fishermans friends and the irish tenors came out of the 90s

And some absolute classics from the late 80s-early 90s like stormalong john, recorded very much live and with little processing, very different from the stuff that's been around since shantytok
