This 1973 LP is a bit of an oddity in the Sonny Stitt catalogue. The Paula release combines soul-tinged numbers (complete with female vocal backing) with some straight-ahead jazz tracks in an obvious attempt to appeal to both the R&B and jazz markets. Unfortunately it failed to attract much attention from either.
Soul Girl has had two releases on CD, one on a Japanese reissue that is still available if you'd like to part with about $30 of your hard-earned cash. The other was on a now deleted disc titled I Should Care, released on Jewel (a sister label to Paula) in 1996. Copies of this release, both new and used, can be had very cheaply in the Amazon Marketplace.
You can grab a sample track, taken from a 1973 cassette version of the album, from the link below.
