Here's what real influencers do: If you're Carl Perkins, every song on your first LP was covered by Beatles. If you're Muddy Waters, the Rolling Stones named their band after one of your songs.. If you're Chuck Berry, you influenced anyone who has ever considered themselves rock'n'rollers. And if you're Johnny Cash, you were the original Outlaw Country artist, and you invented the country-rock nexus.

Hard rock in the 1970s was mostly a game for dudes. Although Janis Joplin and Grace Slick had broken through in the 1960s with major rock hits, Coven lead singer Jinx Dawson had gained some notoriety, and Fanny (one of the first all-female rock bands) had some success, the rock charts were male dominated. Enter the Wilson sisters, Ann and Nancy.

The first headphones I owned, circa mid-1970s, were made by Pioneer. They jutted out from my ears, with small, paper-cone speakers inside. "Head-Fi" is a whole different world nowadays than it was back then. The biggest change is Bluetooth, which lets us untether ourselves from our stereo systems.

There are craftspeople and companies in high-end audio doing admirable work. Those at the cost-no-object end of the business are pushing performance limits and doing new and better things with new and better materials. The ones I especially admire, though, are in the high-value end of the business, making extraordinary equipment at approachable prices.

In the Rolling Stones' long history, the Mick Taylor era was a peak, if not the peak. Taylor, who replaced cofounder Brian Jones in the late 1960s, proved a great musical foil for Keith Richards. He was a technical wizard on the guitar; those fluid higher-octaves riffs and runs were the perfect counterpoint to Richards's jabbing and stabbing and growling style.
