First from Last Exit... 1975 [FLAC limited time only]

With Gordon Sumner = Sting.  I think everyone can instantly recognize his unique voice in fact, anyone who might be older than about 35 maybe, that is, millenial or Gen X or god forbid baby boomer?  (I certainly would never ask a Gen Z to identify him.)

This band existed as of 1974 and I suppose was the first for bassist Sting (aged 23 at the time), with this cassette release from 1975 in the jazz-rock territory it's unusual to say the least.  It definitely surprised me, partly because it's quite approachable and listenable, with horn rock songs for the most part.  You'll note some of the later Police harmony vocal patterns on On This Train #2:

I would go so far as to say almost every song is not throwaway, showing the youthful creative energy you always encounter with music and musicians.

Album closes out with the lovely instrumental A Bit of Peace:

Huge surprise for me, who has never been a Sting fan and probably never will be without a head injury. Apologies to those who are.
