an album by Chris Thile and Edgar Meyer named Bass & Mandolin has lots of deep double bass.
"Love", the fourth track from the 1971 Pharaoh Sanders album Thembi.  5 minutes of brilliant  stand-up bass playing by Cecil McBee. The engineer of this recording got everything right.  Sounds like you are inside the bass. You can feel the wood of the instrument vibrate. My go-to for testing bass and imaging.
