I've received a response from LANDR regarding my song release. It would appear that a quite serious precedent has been created here that could potentially impact on anyone who creates music that includes BIAB Realtracks and attempts to release it through LANDR.com.

Despite PG Music confirming that I have permission to freely use BIAB in my recordings, LANDR have identified the artist who provided the recording for one of the BIAB Realtracks (ie. the sax), and are informing me that they are unable to go ahead with my release without proper authorization from the soloist Eric Marienthal, in the form of a contractual agreement:

Hi there,

I'm Coleman, sorry for the delayed response!

I have a little question about your release with UPC code 628810692224.​

The soloist you have included, "Eric Marienthal" already has a relatively established online presence.
LANDR cannot release tracks without the proper authorization for this artist.

In order for us to move forward with this release, we'll need you to provide us with a contractual agreement stating the terms and conditions of the collaboration for any licensed content.


I know it seems like a lot but we just want to ensure you are protected down the line.

Let me know if you need any help with this.

Regards,
Coleman

Hi again,
Further to my reply on 8th Sept, here is confirmation from PG Music that
I have permission to use Band In A Box Realtracks in my recordings. I
hope that the release can now go ahead without any further delay.

Please can you confirm that I have permission to use BIAB Realtracks in
my latest song release. I'm releasing through LANDR.com but they have
put the release on hold as they have detected possible third party
content when reviewing it and have emailed me asking for confirmation
that I have permission to use any copyrighted material. I know that I
have because I've read your FAQ (https://www.pgmusic.com/salesfaq1.htm
<https://www.pgmusic.com/salesfaq1.htm> #22), but it would be
helpful if you can also confirm this here so that I can send it to them.

Anything you make in the program is yours to do with as you please as
long as it doesn't infringe on the intellectual property of others or
include our demos, since the demos are copyrighted by us. Anything else
is free game.

Andy Shearer 4:17:55 PM
Thank you Deryk. I will send them a transcript of this conversation and
hopefully my release can then go ahead.

Deryk 4:18:42 PM
Ok, sounds good Andy smile

Andy Shearer 4:19:37 PM
Thanks again. I appreciate your help Deryk.

Deryk 4:20:05 PM
You're welcome, happy to help smile


I haven't a clue how they managed to identify the Realtrack soloist, but I wouldn't know how to go about contacting Eric Marienthal to seek his permission, let alone obtain a contractual agreement stating the terms and conditions of the collaboration for any licensed content.
I'm quite surprised and disappointed with this outcome, and I think that I'll just have to cancel this release altogether and maybe re-record the song without the sax solo.
