that really doesn't effect enough of it to warent any real fix. it's less than a second and only effects the timpani roll.
It is present in the SE and the Anthology. You can barely tell, but if you compare the two, it was a recording error. You get that same sound in the timpani in both. Mine just makes it more obvious because I've raised the volume and made the recording clearer and brighter.
You have to remember that these are mixed live as it's being recorded. That timpani roll must have caused a small problem when recording it...
