Miles live on the comeback trail. It’s easy to view this music as a continuation of what he was doing in the 1970s, but slicker, lighter and with a newly airy pop sensibility. However, “Kix” and “Fast Track” are pretty weak and there seems to be no need for two versions of “Jean Pierre” here. Miles struggles to find his footing some of the time. Oh well. This one’s a fair effort. But it feels more like a victory lap than the race itself.
