In fact, the same is wrongly spelt: the conductor's name is Vitaly Kataev (not Kitaev). He was a Soviet conductor who mostly worked in Belarus (though he was born and died in Russia). Here are the Russian and Belarusian wikipedia articles on him:
https://ru.wikipedia.org/wiki/Катаев,_Виталий_Витальевичhttps://be.wikipedia.org/wiki/Віталь_Вітальевіч_КатаеўHe recorded quite a number of orchestral works for Melodiya, mostly by Belarusian composers.
Vorobyov, in turn, is an obscure figure due to his early death but I heard his symphony before and it's really nice. Some information on him can be found here, for instance:
