Though ‘09’s autumnal equinox came and went a little over three weeks ago and the air’s slowly but surely getting chillier (at least up here in Minneapolis), there’s still time to bid warm weather one last farewell. On Summer’s End, the latest official leak off Cause‘s forthcoming I Am Us mixtape, the reader-acclaimed South Bronx lyricist does just that, waxing nostalgic about what he calls “the best times in [his] life.” Cause’s wistful verses, which see him savoring vivid memories of long, lazy days spent chilling with his crew and warm, party-filled nights, are sure to leave Booth readers impressed, as is Sean Divine‘s headphone-worthy beat, which blends resonant piano chords with subtle electronic accents. As if all that weren’t enough, the artist showcases his musical versatility with a mellow, sung hook. Will this be hit number three in the hot streak Cause established with In Too Deep and In a Daze? I can’t see why not. Like the autumn leaves, I Am Us is set to drop this fall – no raking necessary, of course.
