Swans

If the grifters who currently own the copyright to Marvin Gaye's music also owned the rights to the music of David Bowie, they would sue Michael Gira over the  final 6:00 minutes of Swans' new single I Am a Tower for its resemblance to Bowie's Heroes. 

But they don't, and Bowie himself would have recognized that the evolution and development of creative music as an art form necessarily includes references and homage to previous works. And as far as theft of intellectual property goes, no one can reasonably claim they purchased I Am a Tower thinking it was Heroes, nor does Tower's appeal lie solely in the resemblance in its closing passages to Heroes. If anything, Tower may incentivize a new generation of listeners to go back and listen to Heroes.

Not to mention that the spoken word vocals at around 3:45 sound reminiscent of The Doors' Horse Latitudes. 

But this discussion already loses sight of this epic, 19-minute powerhouse drone meditation by Swans, the first single from their upcoming Birthing LP, to be released May 30.
