You could do that forever and not get a break, you need the following:
1: the right image and sound, demons/other spirits can tap into what label execs are looking for, for their plans 6 months down the line, and you need to be able to see and hear them well enough to pay attention and get the message – I don’t mean you need a manifestation strong enough to pop up some shelves and leave dirty footprints on the mat, but you DO need to be able to understand what they advise;
2: to meet the right person under the right circumstances, this could be playing in a club, or some chance meeting, you need to know where people like this hang out, where they signed their last 5 – 6 acts from, because you can gig worthy clubs until you’re blue in the face and die of burnout, and so do all the fans who tell you how great you are, and what a shame those bastards never gave you a chance;
3: have an inspiring, captivating, charismatic stage presence AND at least the seedfs of a strong image that plays to YOUR strengths, recognisably enough like something people have already seen but also unique, and able to branch off into your own thing, with time (you will get stylists thrown at you, but the seeds of your own creativity will catch the eye);
4: have some songs that are C.L.A.S.S.I.C.S – think, Eleanor Rigby, Losing My Religion, Wichita Lineman, that thing where the first bars make millions of people immediately recognise it’s you, and carve out a place in history (plus maybe ad revenues later on with some of your hits).
Later you can get spirits to literally possess you going on stage before tens of thousands of people, replacing drugs and crap like that, so they get to drink all that lovely fan worship and you come across as more than a mere mortal.
Fyi I know a couple of people who worked in the music business and I actually ran this quickly by them (redacted exact details) to see what advice they’d give, I know a bit about this but not as much as them, so I went to a bit of bother for you here and while that doesn’t obligate you to take the advice as gospel, I do request you at least give it some consideration.
That can be done but it’s a poor second or third to other options IMO.
So the simplest action plan for the above is to learn a method of interacting with spirits, either evocation (my recommendation) or soul travel, that will allow you to communicate clearly with spirits, ask and receive answers.
And learn a method of divination as well.
Make a pact with one good strong spirit you trust and ask them to give you a familiar whose primary task is inspiration, he or she will be the one that puts that killer hook in your head that defines the hit songs the guy you meet is going to sign you for, and makes the jacket, haircut, or whatever that defines your early style come into your life, by telling you to check one more thrift store or click one more link at random.
The demon is meanwhile going to assist you, not through “magic” like Harry Potter, through advice and your own willingness to be out and about, to find ways to get in the presence people who can help you, in ways that mean they will notice you.
Again, you’re going to need to understand what the demon advises, and you need to meet people like crazy, go to parties (don’t use this as a chance to get fucked up) and above all be professional, positive, punctual, help other people when you can, and be the kind of person people want to be around (amazingly few people in the creative arts can accomplish this).
Does this sound like something you’re willing to try?
Varnaxis is a good guy to contact for this, he may or may not be your main pact long-term but he knows his way around making a successful life from nothing, he can probably assist you.
You can be, do, or have ANYTHING you desire, but you have to be willing to do what it takes.
