Vincent Montana Jr. has contributed to the Philly soul/disco sound as a composer, arranger, bandleader, percussionist and producer. He's associated with tons of great music by MFSB, Salsoul Orchestra, Goody Goody and many others but if I would have to choose one track by Vincent Montana Jr, I would probably pick Heavy Vibes. To be more precise I would take Paul Simpson's club mix. If you're interested in Vince Montana's work in the late 70's / early 80's, I highly recommend this 3LP.
