Candi Staton has experienced a resurgence in popularity in recent years thanks to a really good record produced by Will Oldham and re-issues of her soul music from the 60's and early 70's. This track is from 1979 and is produced and co-written by Patrick Adams. (The band is ingeniously credited as the PA Sound System.) Patrick Adams has also received his fair share of attention recently thanks to slew of reissues from his P&P Records label. The really cool kids have always liked him because he was the engineer on Eric B. and Rakim's Paid In Full.
This version of When You Wake Up Tomorrow is the "Disco Mix by Jimmy Simpson" (brother of Val) and it's really friggin' good. I especially like the synth part towards the end.
For those of you thinking: yeah, that's cute, but I know this track - I'm including a more obscure Staton track from 1982 on Sugarhill Records called Love And Be Free which (in addition to being great advice!) is a zippy little track with a wicked 80's guitar part.
