As close to indie rock royalty as may exist, Ira Kaplan of Yo La Tengo–a band nearing its 40th year in existence that he founded with his partner, drummer Georgia Hubley in the mid-1980’s–has recorded 17 records under that name and influenced more bands than could be named here. Simultaneously considered critics’ darlings but also having established a wide, loyal, and sustaining fanbase, the band–anchored by bass player James McNew–will perform with the Sun Ra Arkestra at the Big Ears Festival in Knoxville in March. In this episode, he discusses how songs by Half Japanese, the Grateful Dead, and The Tremeloes guided his development.
