This perennial favorite continues its stranglehold on this category for two simple reasons: They stock things you can't get anywhere else in town, and the staffers know their shit. Whether it's a Houston or regional title, import, long-lost record your granddad had, or an obscure EP by Death Cab for Cutie, you can find it at Cactus. If not, they'll order it for you. The store has also started a "Build a Better Music Library" sale that encourages patrons to check out original classic albums on CD rather than buying greatest-hits compilations. And though toys, shirts, videos and knickknacks take up a good chunk of floor space, Cactus still has the widest and most eclectic selection of music anywhere in Houston. Its LP and vinyl business has increased over the past year. Time to reorder those fuzzy black record dusters.
