  "abstract": "We determine a universal sector of the spectrum of light operators in four-dimensional $\\mathcal{N}=1$ class $\\mathcal{S}$ superconformal field theories arising from M5-branes wrapped on a compact hyperbolic Riemann surface $Σ_2$. We work at large $N$, analysing Kaluza--Klein fluctuations about the dual Bah--Beem--Bobev--Wecht anti-de Sitter backgrounds for general values of the twist parameter $z$. To obtain these spectra, we specialise recently derived mass operators to modes that are constant on $Σ_2$ by imposing a suitable $z$-dependent generalised $G$-structure. We then organise the resulting eigenstates into long and protected $\\mathcal{N}=1$ supermultiplets with definite flavour quantum numbers. As $z$ varies, rich patterns emerge in the spectrum, including both isolated multiplets and infinite towers of multiplets, which we characterise analytically.",
