One of the things I did about Richard Bona is he is Musician first and monster chops player second. Here he's backing up Janis Ian and just laying it down with a few harmonics and then hangs a great chordal ending on the tune.

That's what makes Marcus, Victor, Richard, Patatucci, Flim Johnson and others great is they have all the chops, but play what the music calls for. Marcus' work with Luther Vandross are great lessons in playing bass lines that make the song. Sure as bass player checking out some bass pyrotechnics is fun, but to me gets old quick. Rather listen to a great bass part or a solo that says something.
