Master is a thrash metal band from Russia, founded in 1987 by Alik Granovsky, Alexander Bolshakov, Kirill Pokrovsky and Igor Molchanov who left heavy metal band Aria because of conflict with their producer Victor Vekshtein. Vocalist Mikhail Seryshev and guitarist Sergey Popov have joined them to play live concerts. Their first self-titled release was half-completed by Aria's songs written by Granovsky and Bolshakov, but later they turned their music from Aria's NWOBHM-like style to the first thrash metal in Russia.
