The Michael Schmidtmusic industry has lost a beloved member.

Lasse Wellander, the longtime guitarist for the band ABBA, died on April 7 after a brief battle with cancer, a message on his personal Facebook page confirmed. He was 70.

"It is with indescribable sadness that we have to announce that our beloved Lasse has fallen asleep," the April 9 statement began. "Lasse recently fell ill in what turned out to be spread cancer and early on Good Friday he passed away, surrounded by his loved ones."

"You were an amazing musician and humble as few, but above all you were a wonderful husband, father, brother, uncle and grandfather," the message continued. "Kind, safe, caring and loving... and so much more, that cannot be described in words. A hub in our lives, and it's unbelievable that we now have to live on without you. We love and miss you so much."

ABBA members Agnetha Fältskog, Björn Ulvaeus, Benny Andersson and Anni-Frid Lyngstad also paid tribute to the musician.

"Lasse was a dear friend, a fun guy and a superb guitarist," the Swedish band wrote on Instagram April 10. "The importance of his creative input in the recording studio as well as his rock solid guitar work on stage was immense."

"We mourn his tragic and premature death," their statement continued, "and remember the kinds words, the sense of humor, the smiling face, the musical brilliance of the man who played such an integral role in the ABBA story."

Lasse started collaborating with ABBA in the '70s and toured with them for the latter half of the decade. Most recently, he worked with the group on their 2021 album Voyage, which was nominated for two Grammys.

As ABBA concluded their tribute, Lasse "will be deeply missed and never forgotten."
