Peter Gunn Jazz xylophone

The group that plays at Mother’s has a xylophone. I don’t recall hearing one in Jazz.
Was that popular in the second half of the 1950’s?

Was it a Vibraphone?

It seems the use of Vibraphones and Xylophones goes back to the early days of jazz.

Lionel Hampton, great jazz artist comes to mind.

As does Modern Jazz Quartet.

Thanks, all.
