There's nothing particularly "experimental" or ground-breaking about Internal Wrangler. Guitar, bass, and drums are the predominant instruments, with flourishes of organ and tinny drum samples thrown in. There are no microtonal guitar solos or squelching analog synthtones. The true beauty of Clinic is that they have, using a relatively standard rock vocabulary, constructed a truly distinctive, energetic, and magnetically appealing sound. "Voodoo Wop" opens Internal Wrangler with layers of drums, including bongos, which build upon a slinky bassline and snippets of ambient noise. Coupled with budget reverb that lends a garage-rock aesthetic, the track creates a wall of tension and uneasiness. But it isn't until the record's second track, "Return of Evil Bill," that Clinic unleashes their secret weapon: lead singer Ade Blackburn.
