Mama Sonic are a four-piece band from Stockholm. They have been credited with the creation of plonk, a musical sub-genre combining elements of British indie-rock and punk rock. Formed in early 2015, they have released one EP to date, entitled Plonk, and plan to release a second within the year. They have recently released their first music video (set to the track Amasonic from their debut EP) and are scheduling promotional tours in Scandinavia and Germany over the summer. Mama Sonic consist of childhood friends, Jacob Hallerström, Olof Niklasson and brothers Richard and Martin Wedberg. The four previously rallied behind frontman Jacob Hallerström's self-titled project, which ran from September 2013 until the end of 2014 and released one EP, Inner City Postcard. The group at that time played a mellower sound more akin to indie folk-rock, but decided that a rebranding and change in musical direction was needed Reformed as Mama Sonic, with a stronger musical and visual identity, they have proven far more powerful in establishing their presence on the Swedish underground music scene, atttracting positive reviews from a range of well-known indie publications. Mama Sonic were signed by indie label ADSRecords in spring 2015. <a href="https://www.last.fm/music/Mama+Sonic">Read more on Last.fm</a>.
