No doubting Philly Internationals credentials as soul music IMHO - just as Motown was pop / soul selling to the masses in the 60's - PIR was one of the labels at the top end of soul music in the 70's. Because of the sheer output of these labels there was always going to be the ' misses ' that found favour in northern / rare soul rooms.
The ' I Love Music 's ' of the label personally wouldn't sit right in a rare / northern room for me but as posted, there are many many great 45s / LP cuts that sit perfect in modern rooms etc
Plus - for me Motown / Philly / Atlantic / Stax - the big 4 so to speak got me into this whole thing of rare soul in the first place . The perfect stepping stone from the big commercial end to delving deeper into soul..
Cheers
