The new book by Graeme Thomson answers many of the questions Simple Minds fans have had for decades. In Themes For Great Cities, Thomson explains (with participation from almost all band members past and present) how their artistically challenging beginning gave rise to their commercial peak in the mid-80s. What were their influences, how were songs like "I Travel" and "Love Song" even constructed, and what was behind the good and bad decisions the band made along the way. Theme is manna from heaven for SM obsessives because as enjoyable as the band is to listen to, they're equally as enjoyable to discuss.
