I would second what Dagger says here. Colin gets a great tone from his mandola and he has got his recording technique well sorted out too.
If you are just looking for recordings of Irish Mandolin then you should check out Aidan Crossey.
He has a site with loads and loads of tunes and also the tab.
He has changed his website layout and it's a little confusing.
Go to this link: https://theirishmandolin.com/learn-some-tunes-2/
Then click on A to F -or- G to M -or- N to S -or- T to Z in the green bolded font.
It opens to a new tab with the tunes, recorded on different types of mandolins.
