At some point, a man must consider shifting the manner in which his abode represents his love of music -- blacklight posters scream immaturity, and why even bother painstakingly piecing together Tiger Beat collages if they aren't going to showcase 98 Degrees anymore? For adult-er musical adornment, check out Bughouse.
Dedicating a good deal of their artistic output to crafting furniture and wall decorations inspired by old albums and musical instruments, Bug's the baby of a California couple who've spent the last 10+ years "subvert[ing] the expectations placed on functional objects", an accurate description of your college years, minus the "functional", and actually, the rest of it. Things kick off with two rectangular side tables, made from canvas encased in poly resin and featuring "faux-album imagery", with the smaller faces featuring images of authentic vinyl cover art, and the top and other sides made to look filled with stacked album spines; there's also a knotty pine coffee table whose surface is covered with a photo transfer of a vinyl DJ layout (2 turntables & a mixer) protected by clear coat -- just as people with ears will be by the rig's not-realness. Wall options include a wide range of gallery-wrapped canvased prints of dozens of album spines, organized by musical theme and medium, including the vinyl "Smooth Sounds of Easy Listening" (Manilow, Frankie Avalon, Bread, etc), "Hip Hop Tapes" (Maxi Priest, Wrecks-n-Effect, Keith Sweat), and "8-Track System", a player and speakers piled with stuff like Styx, Devo, and Cheap Trick, which pretty much sums up the format.
There're also wooden blocks with heat-transferred images of either a turntable or Fender amp, and some giganticized wall art featuring also-faux collections of up to 1000 record spines, the kind of output you could only dream of from a certain high-temperature boy band.
