In my estimation, for Barking, they made a conscious decision to make it a more traditional (accessible?) "album." All the songs are more traditional song length (4-6 minutes), and have a more traditional song structure, and no mixing of the tracks.
In fact, we know that some of the tracks are longer in their full form. For example, ALAF clocks in at
8:34 in its full form. And appleblim has said that Hamburg Hotel is much longer in its full form. Which confirms what many of us thought when we said it sounded like it was just getting going as it fades out on the album. So I can only assume that it was deliberate calculation to edit and present them as they are.
If you want epic (i.e. long) tracks, you don't have to look back too far. "Peach Tree" is 12.5 minutes, and "Ancient Phat Farm Coat" is almost 20 minutes. Or "Dreeve" and "Van Halen Van Halen" on Bungalow with Stairs. Granted, those are older tracks, but recently released.
