| Liad,
You can check out the recordings of Niklaus Eklund. He's got a multi-volume CD set of Natural Trumpet repertoire released on Naxos. Naxos has a free audio streaming service on their website (you have to register on the site I think). His playing is some of the best I've heard. You can also check out recordings of Crispin Steele-Perkins (England). Barry Baugess (American) gave a nice lecture recital on natural trumpet at ITG this past summer as well.
Google "Natural Trumpet" and you're sure to find even more resources.
