Twenty-five tracks from her prime, recorded for Modern in the 1940s and '50s, including her hits "That's My Desire" and "Out of the Blue," as well as "Anytime, Anyplace, Anywhere." While Brooks was an important figure of the L.A. 1940s R&B scene, latter-day listeners may find this rather tame. Vocally she owed much more to pop-jazz stylings than gritty R&B influences. Her most durable and influential performances were her instrumental ones at the piano bench, especially on the pounding "Swingin' the Boogie," which leads off this collection.

While Ace's previous Hadda Brooks disc, Romance in the Dark, concentrated on her excellent mellow vocal sides, it left the instrumental boogie-woogie aspect of her musical talents unexplored. Swingin' the Boogie corrects that with this amazing release. Brooks recorded many of these tunes for the Modern label, initially released on 78s. Often after the "official session" concluded, there was still studio time available. In these instances, Brooks would pound out amazing boogie-woogie tracks for kicks. Swingin' the Boogie is the first disc to focus entirely on that output. Among the 18 tracks, six were previously unissued, and it includes the rare original flip side of "Swingin' the Boogie," "Just a Little Blusie."
