Tyler and Maggie Heath, siblings from San Marcos, Texas, self-released their independent album, Through the Deep, Dark Valley, in October of last year. It was the culmination of a collaboration that began a couple years ago, when they wrote their first song together — for their mom. She liked it, but more importantly, they liked the process.
The two value working as independents by choice — they produced Through the Deep, Dark Valley themselves — and, based on the sophisticated layering of their songs, I'm not sure how much an outside producer would improve things.
