I Didn't Know About You is the debut studio album by American jazz singer Karrin Allyson.

Part cabaret, part Cassandra Wilson, Karrin Allyson has a lovely musical range and a sharp, clear, slightly nasal voice which is capable of stunning scat and other instrumental effects as well as the straight, lyrical approach.

She primarily utilizes top Kansas City musicians (including pianists Paul Smith, Russ Long and Joe Cartwright, guitarists Danny Embrey and Rod Fleeman, bassists Bob Bowman and Gerald Spaits, drummer Todd Strait, cornetist Gary Sivils and flugelhornist Mike Metheny) on a variety of bop-based material.

Among the highlights are 'Nature Boy,' Karrin's chancetaking duet with drummer Strait on 'What a Little Moonlight Can Do,' a rapid version of ''S Wonderful' and a bossa-novatized 'It Might As Well Be Spring.'

Karrin Allyson, who also plays piano on three numbers, shows a great deal of potential throughout her rewarding debut.
