Chimera is a band on PA  http://www.progarchives.com/artist.asp?id=5780" rel="nofollow - http://www.progarchives.com/artist.asp?id=5780

It has a very sad story as the two girls in the title recorded the album in the 60s but it wasn't actually released for a number of bad coincidences, including a serious car crash involving Lisa.

It features members of FLEETWOOD MAC (George WESTON) and PINK FLOYD (MASON and WRIGHT) and was produced by NICK MASON.

In 1996 Francesca and Lisa wrote a book about their experience in making the album, from their beginnings as Beatles' groupies to when they met Nick Mason in Rome in 1968 in the backstage of the "Palasport". 

The tapes were discovered by coincidence 30 years after and the album was published in a limited edition in 2002 and reprinted on CD in 2004. Sadly, Lisa passed away in 2003. 

The only survived copy of the book was in the public biblioteque of Perth (Australia), available only for rent.

Some years ago I tried to get in touch with Francesca but with no success.

Now the has been reprinted and published as e-Book. I will write a review as soon as I have read it. 

Sample tracks from the album are available on youtube.
