Eino Matti "Eicca" Toppinen (born 5 August 1975) is a Finnish cellist, songwriter, producer, arranger, and (as a hobby) drummer. In 1993 he formed the quartet Apocalyptica.
Toppinen grew up in Vantaa's Hakunila and has three sisters and one brother, all of whom took instrument lessons while growing up. He started playing cello when he was nine. He and his sisters made several amateur recordings for their family, usually for Christmas.
He attended the Sibelius Academy in Helsinki, where he met future Apocalyptica band members Paavo Lötjönen, Antero Manninen, and Max Lilja. He played for several orchestras, including Finnish Radio Symphony Orchestra and Avanti! chamber orchestra. He's also a founding member of the Sibelius Academy's Cellosextet. When attending Sibelius Academy, Eicca could not get an apartment or student support money because he lived too close to Helsinki, where the Academy resides.
