Here are a couple of offbeat but in my opinion great jazz discs, made of of unusual duo's.
* The first, which from a search of threads appears not to have appeared here yet is a SACD/CD called "Superbass 2". It is a sequel to any earlier 2006 release entitled "Superbass". It is a trio consisting of three bassists - Ray Brown, Christian McBride, and John Clayton. On two tracks they are aided by a bit, but just a bit, of percussion. The album covers standards and some really neat originals, which cover the gamut from ballads to swinging tour-de'forces. Sound boring? It's not .... try it. Telarc SACD 63483.
* The second is an album featuring saxophonist Houston Person and bassist Ron Carter. They have played together off and on for years, and cover everything from standards to a couple of originals. As much as Superbass swings, these two are modern cool .... but extremely musical. Houston is a superb solist and Ron Carter an accomplished bassist, and they clearly are on the same musical wavelinks. HighNote HCD 7315,
If you want a break from the usual, give these two a whirl!
