Who as I bought the album in 1980, will probably have been surprised just be much more accessible by the highly complex compared to previous album 'Hemispheres' pieces. Only the 9minĂ¼tige highlight of this album, 'Natural Science', continues the tradition of dodgy-genius longtracks fully continued. Another highlight is 'Freewill' with one of the best guitar parts of rock music and Geddys followed falsetto with goosebumps guarantee. 4 stars, because there are much better Rush albums.
