Volume 2 This is the logical continuation of Volume 1. The first deals with 20 years of hard rock and heavy metal from 1970 to 1989, this one covers the following 20 years from 1990 to 2009, on the same criteria and the same form. Ie, chronic and often unexpected albums with interesting information supplements. The title therefore makes sense, these two books are but in fact only but still amount to no further than 2000 pages between them. This series is a great success. Have can talk about series because from the introduction of this Volume 2, Volume 3 is announced.
