Flashback is a work of six compositions, all with a common denominator: a look into the past. It took me two and a half years to finish it just as I wanted it. It is a "greatest hits" CD of never-recorded (and sometimes never-composed) music. During this process, I have rediscovered several worlds which I had previously abandoned, I have been able to discover new ones and it has been an excellent opportunity to meet old and new friends. This CD was recorded in several studios, but two have special significance. The first is Tarkus. This studio is owned by Juan Ricardo Weiler, one of Chile's progressive heroes and a dear friend who is always willing to help his fellow musicians. It was here that we recorded the drums, some guitar and bass. The second studio is Opus 125. This studio is my own and sacred work place. Opus 125 is where I composed and arranged Flashback. Here I recorded the keyboards, some guitars, and did all the mixing. The artwork was done
