I've always admired of how well piano players can play changes with walking bass lines. It's not so easy to accomplish on vibes. The way I attempt this requires some mallet dampening to keep everything sounding full and clean.

To get started you might try writing out a walking line to practice with, but ultimately you want to be able to create your voicings and "walking bass" spontaneously.

Here is traditional tango very weel played by an authentic argentin player. He is 34 years old, and he plays with a lot of bands in Buenos Aires, some of them new tango (Piazzolla and his musical's sons). Perfect tecnician, and for me the real tango feel (length of the notes, accentuation, lyricism, etc...). He has many albums, and many Youtube videos with this duo.
Hope you enjoy !

Another great player, interesting too. There are others videos of them on Youtube. Hope you enjoy it !

Here what i've got about him :

I disscovered this player, i like his feeling. There is another video on Youtube where he is playing a swinging tune with a 4tet. I hope you enjoy, and it's intersting to see new things..

Well sort of free. I'll give away 2 sets to two people (1 set each) who want to do the following.

I'll be giving away the soft version of the mallets. Great for quiet(er) gigs and practicing.

Do a GOOD report on a living vibe player.
Put up his discography, and get 5 of his latest cds in our amazon section. Gather his important links, youtube vids, tell us something about him. (Don't plagiarize).
