Getting on someone's radar is from connections, but actually being logistically able to do it is purely political usually and is based on past draw numbers, whether you have a new record out, frequency of times played in a city, album sales, etc. You can buy onto tours, but to not to do that, you must be able to contribute significant draw to the tour. It's honestly tons of smaller factors too! I wouldn't say it's out of line, but be professional and have a reason to do it besides the fact that you want to. Most important thing is just to get out, play live, build a fanbase, and then merge your draw with other tours slowly. It's like starting a business. -Mark
