Just make sure you retain ownership of the music itself, as well as your 50/50 split. Also, define ahead of time what you are getting 50% of... net? profit? It's easy for the label to pay their own staff to do a bunch of marketing for you, and claim they have spent all the profits, so your 50% of profits is $0.00.
For sure, I always made sure of the ownership thing in previous contracts. It's only a small label curated by an artist who's been in the scene since its inception. So there's not like there's a load of staff or anything. It's more that they just that they are well respected and know everybody! I believe that they do A+R for a bigger label too. Most of the cost I think will go into the physical releases as they produce vinyls and CDs for the LP projects they release. It's not a label that churns out loads of releases. Instead, they tend to focus on fostering emerging talent with original takes on the genre. So whilst I always be on the look, I don't expect them to do anything to screw me over.
