Weather Report's biggest problem is that their music is too predictable which is obviously a big no-no in this genre. First track is great but I suppose that's been said once too many nowadays.
Despite how influential it is, this album's pretty bad in reality. Obviously, the musicians are fantastic, but aside from Birdland (which is an excellent tune) most of this stuff is 80s fusion cheese.
Heavy Weather is regarded as a fusion classic but I fail to understand why. Birdland is the only song that I truly enjoy, Teen Town has some funky bass parts, A Remark You Made is soothing, and Havona is a decent track but the rest is either boring or forgettable. Pastorious showcases some nice bass playing and there are some cool parts in certain songs but in the end Heavy Weather is a dull and boring listen.
