Instrumentalists you can recognize after 6 bars..?

Oops, can't leave out Bill Pitcock IV, the distinctive guitarist in The Dwight Twilley Band, as well as on solo albums by Twilley and the band's drummer Phil Seymour. He got his sound by plugging a Gibson ES335 into a pair of Fender Deluxe Reverb combo amps, an MXR delay between the two. One of my favorite guitarists, he was a 2-pk. a day man (Marlboro Reds), so of course died of lung cancer (in 2011 at the age of 58).

6 bars is a fairly long space in music.  If it's a solo, who can't you recognize in 6 bars?

Robert Fripp, Keith Moon, Carl Palmer, Frank Zappa, Pat Metheny, Tony Banks, Keith Emerson, Buck Dharma, Jimmy Hendrix, Steve Forbs, Keith Jarrett, ....endless list, as all virtuosos have a specific style, like a voice.
