Question: Do both groups, Chvrches and Anavae, feature a guitar?

<P0-S0> The Mark of Cain (also seen as the initialism, TMOC) are a hard rock, alternative metal band from Adelaide, South Australia. <P0-S1>  Their style has been likened to that of Helmet and Rollins Band, yet this band pre-dates both groups and was influenced by the early work of Joy Division, Big Black and United States hardcore groups. <P0-S2>  The Mark of Cain were formed in mid-1984 by brothers, John (guitar) and Kim Scott (bass guitar), with Rod Archer on vocals and Gavin Atkinson playing drums. <P0-S3>  Before long, Archer had left the group and John Scott took on the lead vocal role and the group has remained a trio ever since. <P0-S4>  The Scotts have been the core of the band which has featured 15 different drummers. <P0-S5>  Since January 2001, former Helmet member John Stanier has been their drummer; he is also concurrently with Tomahawk and Battles. <P0-S6>  Australian musicologist, Ian McFarlane, described the group's sound as "Gloomy, monotonous vocals and bleak slabs of metallic guitar did battle over a lurching rhythm section to arrive at a harsh sound." <P0-S7>  Rod Archer died on 26 February 2016. <SEP> <P1-S0> Anavae (often abbreviated ae, Æ or æ) are an English rock duo from London. <P1-S1>  Formed late 2011, the group consists of Rebecca Need-Menear and Jamie Finch. <P1-S2>  Following their self-released EP "Into the Aether", the band signed with English indie label LAB Records in 2013, releasing a second EP entitled "Dimensions" soon after. <P1-S3>  Their live members consist of Seb Gee (drums), Josh Platt (guitar), Shane Britton (guitar) and Kris Hodges (bass and synths). <SEP> <P2-S0> Vietnam is a multiethnic country with over fifty distinct groups (54 are recognized by the Vietnamese government), each with its own language, lifestyle, and cultural heritage. <P2-S1>  Many of the local ethnic groups residing in mountain areas are known collectively in the West as Montagnard or Degar. <P2-S2>  The largest ethnic groups are: Kinh (Viet) 85.7%, Tay 1.9%, Tai Ethnic 1.8%, Mường 1.5%, Khmer Krom (Khơ Me Crộm) 1.5%, Hmong 1.2%, Nùng 1.1%, Hoa 1%, others 4.3% (2009 census). <P2-S3>  The Vietnamese term for ethnic group is người thiểu số or dân tộc thiểu số (literally "minority people"). <P2-S4>  One distinctive feature of highland ethnic minority groups in Vietnam is that they are in colorful attires whether at home, in the farm, on travel or in the town. <P2-S5>  Many of the ethnic groups elsewhere such as southern part of Vietnam, Cambodia, Laos, Myanmar, China, Papua New Guinea, and many other countries do not wear attractive clothes while engaged in their day-to-day activities. <P2-S6>  The clothes of one group is quite different from that of other groups that adds color to the social landscape. <SEP> <P3-S0> Chvrches (pronounced and written as "churches" in Roman form and stylised as CHVRCHΞS) are a Scottish synth-pop band from Glasgow, formed in September 2011. <P3-S1>  The band consists of Lauren Mayberry (lead vocals, drums, additional synthesisers, samplers), Iain Cook (synthesisers, guitar, bass, vocals) and Martin Doherty (synthesisers, samplers, vocals).
