On July 31, Amazon Music will release Amazon Acoustics, a playlist of cover songs and original music from more than 30 artists.

The latest song to be shared from it is Deer Tick’s Grandfather Song, which was was originally a demo for 2013 album Negativity. While it didn’t make the final cut for the record, John McCauley revisited it recently and finished the song at home in Nashville.

We’re glad he did! Stream it here.
