There used to be a website called Metal for Hire. The website served as a portal for bands and music producers to find session musicians. I have/had a listing there alongside the world’s foremost metal drummers. I wrote ‘had’ because the website seems to be down and has been for a few months now. That’s too bad because MetalForHire.com is/was a strong and easily navigated database of session drummers and other session musicians.
I don’t know whether we can expect the website to be online again soon. If you have any updates, ease let me know in the comments.
