The verb выступать/выступить gets a lot of use in Russian. One of its meanings is “to appear in a public place for the purpose of performing or making a public statement”. It conjugates like this:

Although its forms are regular, the verb itself causes some difficulty in translation because of the noun that often accompanies it after the preposition ‘с’ in the instrumental case. For instance «выступить с речью» word for word means “to appear with a speech,” which sounds quite unnatural in English. Instead we will usually say “to deliver a speech” or “to give a speech.” At a circus performance «выступить с номером» means “to perform an act.” At a kindergarten show “выступить с песней” would be translated “to perform a song” or “to sing a song.”
