After the April 10, 1967, recording session, the Experience spent the next two weeks playing shows and attending promotional appearances in England, including a spot on the BBC television program "Monday Monday" and BBC2's "Late Night Line-Up". Chandler, Hendrix, and Kramer completed the final mixing of "Are You Experienced" at Olympic by 3 a.m. on April 25. Chandler had agreed to audition the finished LP for Polydor's head of A&R, Horst Schmaltze, at 11 a.m., so after a few hours of sleep he prepared a suitable acetate demo and traveled to Polydor. Chandler recalled: "As Horst started to put the needle on the record, I broke out in a cold sweat, thinking ... when he hears this, he's going to order the men in white coats to take me away ... Horst played the first side through and didn't say a word. Then he turned the disk over and played the other side. I started thinking about how I was going to talk my way out of this. At the end of the second side, he just sat there. Finally, he said, 'This is brilliant. This is the greatest thing I've ever heard.'" Horst immediately became an ardent supporter of the album and the band, championing the marketing and distribution of their debut LP.
