How is 4 guys writing all of the music, all of the lyrics, playing all of the instruments, singing the songs, engineering and producing the results, dictating and helping design the packaging, and then touring to promote the album, not DIY?
I know, I know, what "yourself" means, but IMO it can also apply to a band of 4 guys. Frownland opines in 5... 4... 3... 2...
