Henrik & Anna, together with the regular baritone Sofia Hagman (unfortunately unavailable for Denver), won the first ever World Championships for mixed quartets back in 2012 in Germany, and has since topped up with Hillevi from the notorious SA Top-5 quartet ReMix. Hillevi also stands as the inspiration for the quartet name, taking the first letters from her first and last name. However, here in Denver we have borrowed another “old” champ, no other than Rasmus Krigström from Ringmasters, world champions in 2012. All except Rasmus are “southeners” and either born or live in Helsingborg, Sweden, which would – as far as we know – be the only connection between the quartet name and the quartet members… 😉 the Hillbillys are your current European silver medalists and SNOBS mixed gold medalists since May 2025, as well as international quartet champions from the IABS contest in October 2024. The combined number of appearances as a quartet singer on the SAI/SNOBS contest stage is a staggering 124-ish times 😉
Tenor: Hillevi Billinger, Lead: Anna Rosenberg Adlerstam, Baritone: Rasmus Krigström, (Sofia Hagman, Pearls of the Sound). Bass: Henrik Rosenberg Adlerstam
