If you’re a fan of Philadelphia soul, you’ve enjoyed the work of Dexter Wansel. He wrote for and produced such Philadelphia International artists as Lou Rawls, Billy Paul, Patti LaBelle, Teddy Pendergrass and the Jacksons, and he conducted and played with MFSB, whose “TSOP (The Sound of Philadelphia)” was the “Soul Train” theme but wasn't called that for a reason he explains. As a kid working at Philadelphia’s Uptown Theater, Wansel assisted Stevie Wonder, James Brown and other acts. Later he got studio gigs as an early adopter of synthesizers, and his debut album, the much-sampled Life on Mars, showcases his jazz-funk chops and a lifelong passion for space. His stories and memories are a blast.
