Deon, a member of our community asked Junichi Masuda if there were any plans to release a CD featuring MTM （mystery thunder mask). Mr. Masuda replied: "No plans so far... But I'd like to!".
MTM was first presented on Pokémon Smash 43 but the reveal was clouded in mystery and the band members were all wearing complete face masks so it was hard to identify them. Akihito Toda, Junichi Masuda and Shinji Miyazaki are the members of MTM. At least three songs have been confirmed to have been played by them.
