Asian collegiate South Asian a cappella features a mash-up of western and Indian/middle-eastern songs, which places it in the category of South Asian fusion music. A cappella is gaining popularity among South Asians with the emergence of primarily Hindi-English college groups. The first South Asian a cappella group was Penn Masala, founded in 1996 at the University of Pennsylvania. Co-ed South Asian a cappella groups are also gaining in popularity. The first co-ed South Asian a cappella was Anokha, from the University of Maryland, formed in 2001. Also, Dil se, another co-ed a cappella from UC Berkeley, hosts the "Anahat" competition at the University of California, Berkeley annually. Maize Mirchi, the co-ed a cappella group from the University of Michigan hosts "Sa Re Ga Ma Pella", an annual South Asian a cappella invitational with various groups from the Midwest. Another South Asian group from the Midwest is Chai Town who is based in the University of Illinois Urbana-Champaign. Emulating instruments In addition to singing words, some a cappella singers also emulate instrumentation by reproducing instrumental sounds with their vocal cords and mouth, often pitched using specialised pitch pipes. One of the earliest 20th century practitioners of this method were The Mills Brothers whose early recordings of the 1930s clearly stated on the label that all instrumentation was done vocally. More recently, "Twilight Zone" by 2 Unlimited was sung a cappella to the instrumentation on the comedy television series Tompkins Square. Another famous example of emulating instrumentation instead of singing the words is the theme song for The New Addams Family series on Fox Family Channel (now Freeform). Groups such as Vocal Sampling and Undivided emulate Latin rhythms a cappella. In the 1960s, the Swingle Singers used their voices to emulate musical instruments to Baroque and Classical music. Vocal artist Bobby McFerrin is famous for his instrumental emulation. A cappella group Naturally Seven recreates entire songs using vocal tones for every instrument. The Swingle Singers used ad libs to sound like instruments, but have been known to produce non-verbal versions of musical instruments. Beatboxing, more accurately known as vocal percussion, is a technique used in a cappella music popularized by the hip-hop community, where rap is often performed a cappella. The advent of vocal percussion added new dimensions to the a cappella genre and has become very prevalent in modern arrangements. Beatboxing is performed often by shaping the mouth, making pops
