The suggestion by @boxer12 of Old & In The Way is a good one. It was released in 1975 on LP by audiophile label Acoustic Disc, and features excellent recorded sound quality. They were the ultimate longhair Bluegrass band, a real bunch of hippies.
A bass player who was a member of the same band as I in San Jose (though at different times. He was leaving as I was arriving in 1971)---Todd Phillips---went up to Marin County to take mandolin lessons from O&ITW member David Grisman. Grisman told him there were a lot of really good mandolin players, but a shortage of upright bass players. Todd took his advice, and made himself into a very busy professional musician, both as a sideman and as a member of some great Bluegrass bands, working with the likes of guitarist Tony Rice, the late Art Dudley’s favorite flat-picker.
I last played with Todd in 2012 (I believe it was), and use my memory of the live sound of his 18th Century upright German bass vs. recordings of same in my evaluations of speakers and subs. I also use recordings I made (with a pair of small-diaphragm condenser mics directly into a Revox A77) of my Gretsch drumset and Paiste 602 cymbals. Better drum sound than that heard on almost all my LP’s and CD’s!
