After a long journey through the desert, and reformation for the "permanent vacation" album, Aerosmith is back and with this box full PUMP which propels the US charts in the head. Deserved success, since the album is a gem, playing a rock without frills, made to dance and have fun. The sound is good, the songs are linked together without long, short, this is a no-fault that heralds the future success of "Get a grip". A must for any fan of Aerosmith.
