The famous producer Bob Ezrin, who worked with bands like Alice Cooper, Kiss, Aerosmith, also produced the famous 1979 Pink Floyd album "The Wall", that became one of the best-selling records of all time. In an interview with Total Guitar, the producer recalled that the famous David Gilmour second guitar solo in "Comfortably Numb" was made in only one take. Producer Bob Ezrin recalls "Comfortably Numb" solo was done in one take “The second solo in Comfortably Numb, which may be the best solo of all time, is actually a first take. It was so powerful when I heard it and saw him play it. It literally brought tears to my eyes. (And)It has many times since then." “Even though this is a record that I participated in, and by all rights by now should be fairly dry for me, that moment is still, for me, one of the most emotional moments in all of music," Bob Ezrin said. Released in 1979, "The Wall" was Pink Floyd's eleventh studio album and had other famous tracks like "Another Brick in the Wall, Part 1/2/3", "Mother", "Goodbye Blue Sky", "Young Lust" and "Hey You". With an estimated amount of 30 million copies sold, it was the band's second best-selling album, being behind only of "Dark Side Of The Moon" (1973) that sold an estimated amount of 45 million copies. https://youtu.be/x-xTttimcNk Ezrin Born in Toronto, Canada back in 1949, Bob Ezrin produced classic albums like Alice Cooper's "School's Out" (1972), Aerosmith's "Get Your Wings" (1973 - As Executive Producer) and Kiss' "Destroyer" (1976).
