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.
