These transcriptions are available on the internet. Please keep in mind that the artists and their families may still receive income related to their works. If you end up listening to something a lot it may be a good thing to actually buy it (or some other work) if you haven’t already done so!
Sonny Rollins needs no introduction. Here’s his first solo on Tenor Madness. Special thanks to Bert Ligon for the great transcription. You can view more transcriptions at U of South Carolina’s website.
