I don't know if any of these have been mentioned, haven't read the whole thread:
Three Pieces For Blues Band And Symphony, William Russo composer, Siegel-Schwall Band playing, Seiji Ozawa conducting. The entire album side has huge symphonic bass lines, lots of kettle drum. The other side of this Deutsche Grammophon album is Symphonic Dances From West Side Story, which I played once and never want to hear again.
The Embrace, from the album Kiss My Axe by Al Di Meola. I'm not sure how they are doing the huge bass shots, maybe a big drum and synthesizer?
The above need to be played LOUD, through speakers with woofers that can grip the air and shake the room. Headphones won't do.
Unorthodox Behaviour, album by Brand X. Prominent fretless bass work. Great music by amazingly talented players. Who knew Phil Collins could play drums like this?
Sunday At The Village Vanguard, Bill Evans. These pieces were chosen to memorialize Scott LaFaro's bass playing.
Autumn Leaves, from the album Nightclub by Patricia Barber. Mostly a singer accompanied by an upright bass, very fine solo in the middle.
I Just Go, from the album Dig by Boz Scaggs. Deep synthesizer bass notes, and a beautiful guitar solo by Boz.
All of the above are extremely well recorded.
