I haven't heard the Godbear CD by Charlemagne Palestine (with the work Timbral Assault among others). However, I found the CD in one of the many lists presumably from Paul Morley, in relation to his book I haven't read titled Words and Music (via Little Raindrops).
“Has pop burnt itself out? Paul Morley, author of the acclaimed memoir Nothing, takes the reader on an epic drive through the history of music to find out. The drive is inspired by the video for Kylie Minogue’s hit single ‘Can’t Get You Out of My Head’; it’s as if Kylie is driving towards a virtual city built of sound & ideas.
A succession of celebrities, geniuses and other protagonists led by Madonna, Kraftwerk, Brian Eno, Erik Satie, John Cage & Wittgenstein appear in Kylie’s car to give their points of view. Detours & sights along the way include Missy Elliott, Jarvis Cocker, Eminem, Human League, Radiohead, Lou Reed, Now! That’s What I Call Music, Ornette Coleman and the ghost of Elvis Presley.
City of Sound found the book inferior to Anthony Lane's Nobody's Perfect, of all things.
From the web page of lists (which I assume come from Morley's book), here's a subset of what I've heard that I would recommend. In hindsight, listening and liking all this pop music has likely skewed my classical preferences, and probably leads to Charlemagne Palestine. Also keep in mind music like Edgard Varese, Coltrane's Meditations or The Monkees are for specialists only...

And for those who read this far, a couple quotes about Timbral Assault. Jason Morehead:
On "Timbral Assault," you're standing inside a tower as the bells above chime out their song, each one fighting to be heard, but everything coming together in a sound My Bloody Valentine might dream of. The sounds begin to sway and careen and the walls begin to pulse and shift as Palestine dives deeper and deeper into the mass he creates.
Palestine doubted if the piano alone would be capable of unleashing these powers, until he heard what a Bosendorfer grand could do. Before that connection - one that could only be made by physical contact - he supposed the answer lay in electronic music, his beloved carillons he played with his feet in church, or even simply in loud volume. Then he hit those piano keys and depressed the pedals, and learned to live in the overtones.
There is simply nothing like this at all. I don't want to come off too technical, but what starts off as a piano becomes a room of swirling sounds with so many different combinations and ideas that change soley on where your head is placed. It becomes tangible and physical sound. It's by far the most spiritual music I've ever heard.
