1953: mr. o'hearn released a cd in january of this year entitled "so flows the current." according to amazon.com, this is his first release in four years. see: http://www.amazon.com/exec/obidos/ASIN/B000058511/qid=999727262/sr=1-1/ref=sc_m_1/002-8030256-5148814
I expected a little more from the new release maybe it will take a few more listens to sink in. I use his cd's as reference material. Check back to see if you can find Group 87 recordings. That's the first time I heard him and have been hooked since.
