'Sixth Sense' (along with 'Caramba') was the very first Lee Morgan album I ever bought - both picked up as Liberty cassette cutouts bought by mail order - a whole mountain of them must have been shipped from NY and dumped over in Liverpool docks. Since then, both have been major favourites of mine, having picked up the CD versions and good original LP copies. Both sessions have a fire to them that I find very appealing. 'Charisma' I find to be a bit patcher - still worth having though.
I still have the cassettes too !
