"Curtains" is an album full of atmospheres, even if they are quite simple, they make the album very soft and engaging.
It is well known that Frusciante is a very well-rounded and open musician who plays multiple instruments, not to mention the, in my opinion, magical use of his voice. I wouldn’t be able to recommend one song over another because I always listened to this album in its entirety, so the listener's memory doesn't hold onto one or more songs but rather a well-defined idea of music and song.
"John has realized that electronics for its own sake is not his forte and decides to let himself be guided by his acoustic guitar."
"Curtains is a good record that demonstrates how Frusciante is capable of giving a lot when he has little at his disposal."
"With Curtains, John Frusciante has reached one of the highest musical points of his career, with a simple album; but full, brimming, overflowing with emotions."
"The final solo (López + Frusci) exudes Hendrix from every pore, and I’m not speaking negatively."
