The latest episode of the Rocket's radio show featured a commercial for new CDs from the TRio's radio show! There will be three volumes of CDs with each volume containing two CDs. The chorus version of "Rocket-Dan yo Eien ni" is expected to be on there, but the rest is currently unknown. Each volume will retail for 3150 yen. The first volume comes out on February 22nd and features Musashi. The next two comes out on March 29th and April 26th. If you buy on Animate (which doesn't seem to ship outside Japan) you'll get the pilot episode!
