There have been a number of very good performances - Casals, Fournier, Schiff (and I agree that Rafael Wallfisch is very convincing live - especially when he plays these 'in the round') but imho the shining performance is that of Rostropovich on EMI
You are partly right - Weinberg wrote four solo sonatas (and 24 preludes apparently)I think Vainberg (sometimes spelled Weinberg), who was a 20th Century Polish/Russian Composer, wrote some solo Cello works
Not many Composers have written for the Solo instrument.
