This week, composer and educator Iain Carnegie joins us to talk about his favorite Rush song, Chain Lightning. Iain dissects Chain Lightning in a manner befitting his teaching position at the Royal College of Music in London--which is to say you'll learn how the song is arranged, why chord voicings are central to the song's tone, and about something called "the devil's interval." 
 
Iain also hosts a great podcast called Politics of Sound, where he interviews Members of Parliament and other well-known political figures about their favorite albums.
