Query: a true gem

this album is nasty! i am not only a huge fan of acid jazz, i am a tough as hell critic and very fussy about what i listen to. i am also a serious jazz pianist. i have heard this cd straight through at least 300 times and it is one of my top five favorite out of the 450+ cd's that i own. brooklyn heights is one of the best tunes i've ever heard. it is simple, yet cutting edge as are all of the cuts on this album. you CANNOT call yourself a fan of acid jazz unless you own this cd!
