Solange Knowles has penciled in an Aug. 26 release date for her sophomore album, "Sol-Angel and The Hadley Street Dreams." The Music World Entertainment/Geffen project boasts production from Cee-Lo, Q-Tip, Mark Ronson, Raphael Saadiq and Pharrell -- who steered the first single, "I Decided."

Other songs on "Sol-Angel" include the Bilal-penned "Cosmic Journey," "Wanna Go Back" featuring Marsha Ambrosius of Floetry, the Estelle-assisted "Same Song, Different Man," and "Champagnechronicnightcap," alongside Lil Wayne.

In addition, Beyonce's younger sister pays homage to Marvin Gaye on "Ode to Marvin," her version of "What's Going On." "T.O.N.Y.," "Sandcastle Disco" and "Would've Been The One" also appear on the album.

The video for "I Decided" is directed by Melina and features Knowles in settings from "American Bandstand," the Civil Rights movement, new wave and a "Cosmic Journey" atmosphere.

Knowles' 2003 debut, "Solo Star," via Music World/Columbia, reached No. 23 on Billboard's Top R&B/Hip-Hop Albums chart and has sold 112,000 copies in the United States, according to Nielsen Soundscan.
