there are specific moments in songs that give me the chills. for me I dont think there is an album that does it more to me than physical graffiti. maybe it's a nostalgia thing. this was my favorite album from about 12 to 15 years old. the whole part at 3:20 2:14 when he sings "and the wind is crying, from a love that won't grow cold" and jimmy does a quick little run underneath it. 4:41 after he sings "we are eagles of one nest, the nest is in our soul" there is a single note that rings out in the right channel with just a little bit of vibrato. 7:39 when he sings "oh lord deliver me, 'all the wrong ive done" 1:11 when he sings "talk and song from tongues of lilting grace, sounds caress my ear" probably my favorite zep lyrics what are your favorites?
