Fixed menu gets hidden by relative positioned images?

Question

I have the following CSS:

#header-fixed {
  background: url(images/header-fixed-bg.png) repeat-x 0 0;
  border-bottom: 1px solid #111;
  position: fixed;
  top: -70px;
  width: 100%;
  z-index: 1000;
  -webkit-box-shadow: rgba(0,0,0,0.3) 0 0 4px;
  -moz-box-shadow: rgba(0,0,0,0.3) 0 0 4px;
  box-shadow: rgba(0,0,0,0.3) 0 0 4px;
}

.large-bg-1 {
  background: url(images/large-bg-1.jpg) repeat 0 0;
  background-repeat: no-repeat;
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
  background-attachment: fixed;
  background-position: 50% 0;
  position: relative;
  height: 294px;
  width: 100%;
}

I'm using the Parallax background technique (when the background seem to scroll slower than the rest of the page). But no matter how much z-index I add to the fixed menu it still gets hidden by them.

How can I solve this?

Set the other element's z-index to -1
