I have quite a few tracks that I gig with frequently on my solo gigs. Many of them which I did not record myself came from Jazzbacks/Soulbacks. The products are well recorded, mixed and performed with easy to guess forms which make it possible to play melody and blow over them first time out. If I could make one suggestion, when it comes to a play along track, simpler is often better. As iconic as some lines and horn parts might be, in a one man band setting “less is more”. When I need a tune, this is one of the first places I go to look for it. Kudos🎶
