Glenn Underground returns with his first album proper in some six years in a collaborative release between his own Strictly Jazz Unit imprint and the Circular Motion label. Whilst Glenn dropped a classic refix of Erykah Badu recently, his inclusion on Rick Wilhite's Vibes New & Rare compilation was let down slightly by some corny kung fu sampling. Underground Legacy Of The Know more than makes up for that with eleven tracks of vintage Glenn Underground productions. The opening jazzy leanings of "7th Trumpet" set the tone for what to expect with the sweeping piano melodies and searching pads that characterise the opening bars soon engulfed by a power sax! From here, Underground introduces vocalist Consuela Ivy on "I Am Not In Love (I Jus Wanna Dance)" one of three tracks featuring her soulfully deep delivery which fits the tight house leaning perfectly in each instance. What really impresses throughout is Underground's mastery of instruments, with the heavy Rhodes organs and string movements that pace out the vintage deep shimmer of the title track providing the album's most rewarding moments.
