How can I know which bands/singers has Super Fans rewards?

[user-removed]

Hi! I heard about the Super Fan thing and read the threads about it here but I still have an unanswered question. 

As a Spotify staff member wrote earlier, not every band has rewards for these super fans, so... how can I know which bands/singers has rewards for them? Is it a public information or not?

Also, I noticed that a upcoming Deep Purple tour date (Budapest) isn't included on their Spotify tour section. Is this means that a free ticket, promotion code, etc reward to the Budapest show isn't an option because of this?

Thanks!
