The three albums change musically as well as thematically. Everett explained to Spinner UK how the musical aspect of each album reflects that particular record's concept. Said the Eels mainman: "Well, for Hombre Lobo, the idea of desire and lust equaled the electric guitar. And for End Times, for loss, I thought it should be more of a traditional singer-songwriter, alone in his basement with an acoustic guitar approach. And then, with Tomorrow Morning originally, my idea was I wanted to do a very warm album, a celebration of the things I like about life and the world. I also had always wanted to make an album that was pretty electronic, but I always thought that would be a colder kind of album because of the nature of the sound - the kind of music that is normally made with those instruments. And then one day it occurred to me: What if I combine these two ideas? The electronic idea and the warm, celebration idea. And then I got excited because then it kinda becomes its own thing."
