Mohapeloa wrote Tsolo La E-sa in the 1930s, publishing it in Morija in 1939 as the eighteenth of 32 songs in Meloli le Lithallere tsa Afrika ka J.P. Mohapeloa: Buka ea Bobeli [African Songs and Extemporary Harmonizations by J.P. Mohapeloa: Book II]. Mohapeloa continued numbering songs in Meloli II - his second songbook - from where his previous book, Meloli I ended; thus Tsolo La E-sa is song No. 50 in Meloli II, not No. 18. This song is not just about the weather clearing up, as it might be in Europe, but about the welcome storms that come in Spring in Lesotho, renewing the earth so that crops and animals - and people - can survive for another year. Thunder can be a sign that a drought is coming to an end. It is one of many songs Mohapeloa wrote about nature, and several that concern the impact of weather.
