Discography from Discogs:
Slick were the instrumental section of Fat Larry's Band. Scored great disco successes in 1979 with jazz-funk classics "Space Bass" and "Sexy Cream" (banned from radio play in the UK). If you want pure disco, though, listen for "Put Your Pants On"...
This gives me an excuse to post a bonus track - the non-Space Disco 'Sexy Cream', which is absolutely fantastic as well:
