Following her 2022 debut LP, "Torn Tapestries," South African singer-songwriter Sió returns with SIGMA, a new album releasing in late June. Created in collaboration with London-based producer Tesfa Williams (formerly T. Williams), the project offers a clear exploration of personal growth, emotional resilience, and self-determination.

Tesfa's beats spoke to every feeling I needed to get out. His quick mind and open heart gave me the space to write something that healed me. I'm done asking for permission. I refuse to settle or compromise. I own my flaws and victories - that's the real rebellion; self-love.
Sió

Written and recorded over four days at Strong Room Studios in Shoreditch, London, SIGMA presents a focused and intentional work. Williams' production balances engaged beats with flowing restraint, supporting Sió's direct and reflective lyricism. The album contains eleven tracks centred on independence, boundary-setting, and healing themes. Singles "Fortnite," "Continents," and "Outside" preview the emotional range of the project, addressing autonomy, confrontation, and renewal. Together, Sió and Williams have crafted a grounded and emotionally deep record.

SIGMA is a clear statement of intent from an artist evolving with purpose and marks the next step in Sió's collaboration with STY TRU BTS.
