Music out there with good bass

Maxwell-Embrya

Check out the thread "Organ CDs with Really Deep Bass."

Roger Waters "Amused to Death". Made my REL Stentor III walk across the room.

Try "The Gladiator" soundtrack. It has some wonderful deep bass notes, but a lot of great french horn.

Stanley Clark "If this Bass Could Only Talk" bass as a lead instrument

Stuart Hamm "Outbound" bass as a lead . . . This also has excellent songs.

Most anything by Bill Laswell.

Massive Attack "Mezzanine"

Tracy Chapman

Gillian Welch "Revival" this is more country-rock flavor, but has some amazing, and different stand up bass lines

For classical music, you might try Edgar Meyer - Bach Unaccompanied Cello Suites. It's performed on double bass and sounds wonderful. It continues to surprise me with its delicacy. Other classical music with strong clear bass is almost any organ work written by Max Reger.

For good vocal bass, you might try Isaac Freeman, especially in his work with The Fairfield Four.

For acoustic bass in jazz music, I recommend starting with Paul Chambers for older jazz, and a few of the albums of Brian Bromberg for more recent jazz. For electric bass, I think Jaco Pastorius has to be considered among the best there has been.
