40 years ago Bill Evans and Jim Hall recorded two brilliant duo albums called "Intermodulations" and "Undercurrent". Andy Laverne and John Abercrombie whose collaboration dates back to the late 1960s have been inspired by the Evans-Hall recordings and have been experimenting with the format. Andy LaVerne remarks, "Over the years we have collaborated as a duo many times in concerts, club dates, workshop sessions. I guess Bill and Jim set a wonderful example to us of what could be achieved by the piano/guitar instrumentation". This LP, though it is neither re-creation nor copying of the original material, is an evolution of the predecessors.
