"Deep" is a Fragile-era song made specifically for the Lara Croft: Tomb Raider soundtrack. Because of this, it has never appeared on a studio album.
The title and lyrics may be related to "Even Deeper."
This is the original version found on the Lara Croft: Tomb Raider soundtrack. A simple song in its structure, the verses feature a loud 4/4 drum loop and a permeating synthesized bassline surrounded by ambient loops. The choruses are distinguished by a permutation of the bassline punctured by wah guitar soloing. Reznor delivers most of the lyrics quite harshly in both sections.
Deep (Radio Edit)
This version is about 30 seconds shorter than the original.
Officially mastered, this vocalless mix was released by Reznor through his remix.nin.com account.
The music video for "Deep" was filmed in May, 2001, and directed by Enda McCallion. The story in the video is told in reverse, with the end of the story beginning the video.
Described above is how the events happened, but the video begins with the car crash and ends with Reznor and his girlfriend deciding to open the boxes.
Blank stare, disrepair There's a big black hole gonna eat me up someday Someday fades away Like a memory—or a place that you'd rather be Some place, lost in space Itch in my head that's telling me somewhere Somewhere, out there, anywhere, I don't care, get me out of here If I could feel All the pins and the pricks If you were real I could take what's apart and put it back together This will come true Help me get through Into you Deep All I can do Driving me through Into you Deep One track, got you on your back Your skin speaks up but your lips couldn't say it Right now, I know somehow We could take the chance and we could make it (make it) Right here make it all disappear Everything that we've been missing, missing You make me feel That there's a part of me That I want to get back again Make this come true Help me get through Into you Deep All I can do Pushing it through Into you Deep All I can do Driving on through Into you Deep You're slipping through I'm coming to Into you Deep We could become Two into one Leave this behind Over and done Everything new I'm getting through Into you
