I have thousands of CDs and vinyls loosely located in the "rock" genre and it's myriad sub-stratas; in recent years I have ventured, with mixed results and some parental guidance, into the classical field. Whilst continuing to investigate, purchase and enjoy much in the aforementioned genres I'm looking for a little help in burrowing into the vast topography of "JAZZ". Notwithstanding already owning and tootling along to the seemingly de rigeur Kind Of Blue and several other Miles Davis discs, plus one of two Gerry Mulligan, Stan Tracey and Dirty Dozen Brass Band albums, I'm looking for someone to shine a little light on a possible path forward. I realise this may be as aimless as walking onto Sainsbury's and asking if they've any food I might like, but all the same. . . anyone give me a head start to happiness jazzwise?
