Lasse Lindgren (b. 1977) played first the violin but on music class in elementary school his teacher inspired the 11-years-old Lindgren to try out the electric bass guitar. The Concervatory of Porvoo and the jamming bands with saxophonist Mikko Innanen coached the young bass player for the Junior Academy of Sibelius Academy and in 1996 he was also accepted to the jazz department of Sibelius Academy.

Few first bands for Lindgren were the Nuijamiehet, founded by Kalle Kalima and Mikko Innanen, and Free Control, whose debut album in 1998 was also the first recording for the young bass player. After Free Control Lindgren played in Jouni Järvelä Group and in Jukka Perko's Hurmio-orchestra. During that time the acoustic bass guitar became "a trade mark" of Lindgren.

In the beginning of 21st century Lindgren founded his own trio, Lasse Lindgren Trio, where, besides Lindgren, played guitarist Teemu Viinikainen and drummer Markus Ketola. A little bit later a band called Brotherhood was also born that offered exceptional Finnish jazz by composing bright songs in major. The band was seen as  something new and different and the debut album Sunburst (2005) was highly appreciated among the audience and the critics. The amount of Lindgren's bands has grown steadily during the recent years. Besides Jouni Järvelä Group, he has played in the band of singer Johanna Iivanainen and Pekka Pylkkänen's Putkipaja. Lindgren has also been on several Vapaat äänet tours, with for example Nuijamiehet, Markku Veijonsuo Trio, Lift quintet and Oddarrang.
