I recently came across this article published by Dave Huffman over at The Indie Launch Pad. It's all about the human connections one makes while working in the music business. Huffman is a great writer on the subject of small business and promotion, whether the business is brick and mortar, internet-based, or one person (or a group) touring the country in a van to play 45 minute sets in clubs and living rooms.
Huffman really gets back to the basic human element of doing business, in this case the music business. If you're trying to make a living off of your music, or any small business venture, I highly suggest his blog in general, and this article in particular.
