People are kinda missing the point here I think. The likes of Derek Ryan are predominately dance bands, who started out playing to dancing crowds. This is by far and away the most successful avenue in the country music scene in Ireland at the moment. Even away from the big bands, plenty of smaller venues run dances every night of the week.
Some of the artists, namely Nathan Carter, have moved to do concerts. For him, this is where the money is. €20/€25 for a 2 hour show per head, vs €15 into a dance for maybe a 3 hour show. Other artists (including Derek Ryan) do concerts too, but not as often.
I think the previous two posters are a little out of the loop in terms of whats popular, and what the people want. believe me, if the people wanted concerts and not the dance shows, the concerts would take over. Supply and demand and all that
I am aware that blues meets country, bluegrass and gospel music all have a massive following too. I am aware of the very good feedback people give when they hear this music often for the first time. Festivals and special events exist and I am always happy to participate and help them out. It is overall more a music for the arts councils, etc. to get behind and is not suited to dancehall venues. With regard to pubs, the right supportive pub can get nice intimate sessions of all types of music going.
