Query: an essential disc

I owe a lot to this disc. It is one of the only CDs I have that I can listen to when going through an emotional tempest. There are no lyrics to cloud your mind, only waves of cutting drum, piano, and a guitar that sounds like it is being played out on the end of a jetty. If you need a good cry, it will draw out the tears. If you need to sit and brood, it will make your time fruitful. If you need to get ready for a long trip at 4:30 in the morning, it will relax and soothe you like a green tea bath. There would have been a hole in my life without this album to take me back to sanity once in a while. One of those albums you thank God you encountered.Thank you for sharing it with me, Tom, even though you were one of the most frequent causes of my listening to it.
