The Jazz Lab Quintet

The Jazz Lab Quintet was co-led by Gigi Gryce and the trumpeter Donald Byrd.

In the autumn of 1953 Gigi Gryce joined the Lionel Hampton Band and they  made  the  legendary European tour.  In Paris he recorded a number of sessions for the French Vogue. There was a number of changes from quartets to a small big-band, but labelled as an orchestra.
