Moses Sumney - Lonely World (Lamentations Version) [Official Audio] bass backing track

A version for learning the line, checking the pocket, and playing along without the rest of the mix getting in your way.

Start with the tricky section, not the whole song. A few good repetitions usually tell you more than one rushed pass from top to bottom.

Once it feels settled, go back to the full arrangement and check whether it still holds together. That is usually where the real answer is.
