When the first season of HBO's Westworld concluded earlier this month, it solidified its status as one of 2016's standout new shows. Created by Jonathan Nolan and Lisa Joy and based on the 1973 film by Michael Crichton, Westworld excelled at melding a twisting, mysterious narrative with stunning visuals and intriguing characters and swiftly broke network records for a debut season.

One significant ingredient that contributed to the show's huge success is without doubt the superb use of music throughout. From the hauntingly epic opening theme song to the saloon piano playing contemporary songs such as Radiohead's 'No Surprises' and 'Black Hole Sun' by Soundgarden, composer Ramin Djawadi did a wonderful job of setting the mood for the entire series and provided the show with a number of musical anachronisms that heightened Westworld's sense of mystery.

As a loving tribute to the show's now-iconic theme song, YouTube channel The Warp Zone have expertly crafted their own impressive a cappella rendition. For the musically uneducated, a cappella means a vocal-only performance with no musical accompaniment and the video features five male singers hilariously dressed up as various Westworld characters including a hairy-chested Dolores, a typically lost looking Teddy, and Bernard complete with his trademark puzzled expression.

The real star of the video is the quintet's vocal performance. The rendition is immediately recognizable for anyone who's seen an episode of the show, and the harmonies on display are near-flawless. The video is also a reminder of how memorable and engaging Ramin Djawadi's original theme song actually is. With many television intro tunes going largely unnoticed, a great theme tune - such as that of Westworld or HBO's other mega-hit Game of Thrones (also composed by Djawidi) - can truly elevate the feeling of spectacle and occasion of each new episode.

Naturally, given its success, HBO has confirmed Westworld will have a second season and while the theme song is almost certain to return unedited in all its glory, fans will likely be hoping the new set of episodes brings a fresh batch of songs for the saloon piano to belt out. After all, guessing which track was playing as Maeve and Clementine pottered about seducing guests almost became a reason to watch the show in itself.

Given how the first season of Westworld ended however, the new season could head in a multitude of different directions when it returns, depending on whether it picks right back up in the aftermath of the season 1 finale's massacre or - as recent reports have suggested - whether the new season turns back the clock and focuses on the guest's experience at the park before Dolores gained sentience. But however season two eventually pans out and whatever new mysteries are thrust upon us, at least we'll always have that brilliant theme song.

Westworld season 2 is currently expected to premiere in 2018 on HBO.
