There are many detailed reports of eisteddfodau and of the harpers who played at them, both in newspaper and official reports.
These are a few examples
Beaumaris Eisteddfod, 1832
To diversify the morning’s amusement, the secretary said he would now introduce one round of penillion singing. Several harpers and singers, apparently peasants, in mean attire, were accordingly stationed on the stage and commenced a kind of singing, or recitation which we believe no person but a Welshman can either comprehend or describe. p. 216
