There seems to be more and more Tropicalia encroaching onto here, and this can only be a good thing. These are the first two tracks from Som Imaginario's splendid debut album, released in 1970. The band often doubled as Milton Nascimento's backing band but come into their own here. Opening track Morse translates to English as morse, so it might be assumed they're referring to the code rather than the detective.
Many of the lyrics in second track Super-God seem to bear little relation to Portuguese at all. There's also a great excursion mid-song into old school EFL learning practice. The rest of the album is well worth investigating also.
