Bart van Strien is based in the Netherlands. I never heard of him before he wrote to Harp-L to point to these videos. He plays old-time music real good, dunnhe? “Sandy Boys” is in 2nd position on a standard D harp, “Give the Fiddler a Dram” is in 1st position on a standard A harp. Both of them sound great–clear, clean playing, with no apparent effort on those fleet lines.
