This is a video work of THE ALFEE's memorable 10th summer event, held at the former site of Yokohama Cosmo Oil in 1991. It is a memorable live performance that also marks the 10th anniversary of the summer event. No one will not be captivated by the powerful opening number "Funky Dog," with columns of water gushing out all at once from a giant fountain set. Rare footage from the past is also shown during "Musician." And the medley of "OVER DRIVE ~Yume yo Hurry Up~," in which the three sing into one microphone while being drenched in the rain, is sure to leave a strong impression on viewers.
